Update "persist" patch to pathauto

Steps to recreate the issue;

- create a page and give it a custom alias. Having "Generate automatic URL alias" checked or unchecked seemed to make no difference.
- go to this page and click "Customize this page" button.
- make some changes and save
- it returns me to the page, with its correct alias that I set previously.
- I visit the page again or reload it, and at this point it reverts to its auto-generated alias rather than the one I set manually. I then have to edit the page (with the usual Edit tab rather than using Panopoly) and set its alias manually again, and because I have the Redirect module enabled I also need to remove the redirect pointing to itself, which causes an infinite loop.

I did apply the patch from https://drupal.org/comment/8674137#comment-8674137 and that solved it for me.

Here is a Behat test for path auto where I tried describing your use case. https://github.com/lsolesen/panopoly/blob/pathauto/tests/behat/features/...

However, I cannot get the test to fail. Did I do anything wrong with it?

@api @javascript
  Scenario: Retain alias when using IPE - Issue #2239847
    Given I am logged in as a user with the "administrator" role
    And Panopoly magic live previews are disabled
    When I visit "/node/add/panopoly-page"
    And I fill in the following:
      | Title               | Testing title           |
      | Permalink           | my-ipe-custom-permalink |
      | Editor              | plain_text              |
      | body[und][0][value] | Testing body            |
    And I press "Publish"
    Then the "h1" element should contain "Testing title"
    Then the url should match "my-ipe-custom-permalink"
    When I customize this page with the Panels IPE
      And I click "Add new pane"
      And I click "Add text"
    Then I should see "Configure new Add text"
    When I fill in the following:
      | Title   | Text widget title       |
      | Editor  | plain_text              |
      | Text    | Testing text body field |
      And I press "edit-return"
      And I press "Save as custom"
      And I wait for the Panels IPE to deactivate
    Then the url should match "my-ipe-custom-permalink"
    When I click "View" in the "Tabs" region
    Then the url should match "my-ipe-custom-permalink"

@dsnopek I thought it would be the same to just click View. Not failing even thought I change to " When I reload the page"

" I think you need to reload the page after waiting for the Panels IPE to deactivate."
Yes, after reloading the alias gets changed, at least for me prior to the patch at https://drupal.org/comment/8674137#comment-8674137 .

I would say though, as far as testing goes... I was dealing with an existing node that I was editing. Not adding a node. Don't know if it makes a difference. My node already had an alias, which I wanted to leave alone, but editing via Panels "Customize this page" and then saving "as custom" even after making no changes, then reloading the page caused the alias to revert to an automatic alias.

      And I wait for the Panels IPE to deactivate
    Then the url should match "my-ipe-custom-permalink"
    When I reload the page
    Then the url should match "my-ipe-custom-permalink"
    When I click "Edit" in the "Tabs" region
    Then the "path[alias]" field should contain "my-ipe-custom-permalink"

Makes no difference. Do not have time to create a patch, but the test is available on https://github.com/lsolesen/panopoly/blob/pathauto/tests/behat/features/... if you want to try it.

Maybe pathauto used to not really save the path properly (hence pathauto_persist), but it has been fixed in the version Panopoly is using now, so we can not get it to fail?

@dsnopek. I haven't yet had a chance to try on a fresh, plain Panopoly 1.2. So it is entirely possible this is down to odd interactions with some other module(s).
