PHP 5.4 test failures

The testbot results linked from the issue summary no longer exist for some reason, so here's a no-op patch that we can use to get direct test results in this issue.

Also I think this should be major rather than critical unless we identity something that's actually seriously broken on PHP 5.4 (but as far as I know there isn't; the test failures are likely to be more minor issues). It would definitely be nice to be able to reliably use the Drupal 7 testbot on PHP 5.4 though.

This should fix everything except UpgradePathTaxonomyTestCase.

I've created 4 sub-issues for the related failures:

• #2660766: UpgradePathTaxonomyTestCase::testTaxonomyUpgrade() doesn't properly test field settings.
• #2660744: Skip test for decoding invalid numeric entities in 5.4+
• #2660754: Invalid numeric comparison in OpenIDTestCase::testConversion()
• #2660762: TrackerTest::testTrackerNewComments() sets the node title incorrectly.

The testbot seems to be having random failures for unrelated things making this more difficult than necessary.

I've managed to convince the testbot to pass all 4 issues above.

There were 4 failures in total. Each issue brings it down to 3 failures. Here's a test to prove all failures are fixed.

Last patch contained some other nonsense.

5.3 and 5.4 are both passing with the related issues compiled into a single patch. I added 5.5 just for fun.

I just ran the patch from #12

• 11 times with the web-5.4 and mysql-5.5 containers with a concurrency of 16 and they all passed.
• 5 times with the web-5.5 and mysql-5.5 containers with a concurrency of 16 and they all had failures.

So this looks to be an issue with the concurrency causing tables to be deleted before they should.

On the old QA system we set the concurrency of Drupal 7 to 8, now we set the concurrency of 31. There were some issues with Drupal 8 and concurrency a while ago, though I don't remember the node IDs.

Fixed PHP 5.4 passes now as far as I can see.
