Submission token description error and suggested improvements

In working with tokens, I found a few issues:

1) webform.tokens.inc, webform_token_info() contains:

  $webform_submission['view-url'] = [
    'name' => t('Update (token) URL'),
    'description' => t('The URL that can used to view the webform submission. The webform must be configured to allow users to view a submission using a secure token.'),
  ];

The name is obvious wrong. Should probably be "View (token) URL" or similar.

2) WebformSubmission::getTokenURL() has an inconsistency. For view, it returns a relative URL, but for update it returns an absolute URL (because it calls getSourceUrl() and that's what it returns. For consistency, the view case should probably be:

        $uri = $request_handler->getUrl($this, $this->getSourceEntity(), 'webform.user.submission')->setOption('absolute', TRUE);

... where the ->setOption('absolute', TRUE) is my suggested change.

3) I went through some effort to add the standard URL token modifiers to the view-url, update-url, and source-url tokens so that I could specify [webform-submission:view-url:absolute]. However if the change to 2 is made, then this probably isn't necessary or needed by anyone. The use case for absolute url's is to include them in webform email handler email messages. I will post a patch for the work I did just to preserve it for anyone else that might want it. I'm NOT suggest this be tested and committed. I am personally not using these tokens as I want ones without the URL query token ?token=xxx. (Confusing using token in two different means here.)
