Fix test failures

Test should now be passing. The failures for non-"next minor" versions appear to be temporary. Testing for "next minor" should be enabled and made to pass.

There is a failure in WebformElementMediaFileTest. The failure is that it fails to find a specific string in the HTML. It could be something simple like the elements being in rendered in a different order. If this test was switched to XPath, differences like that would not matter and the test would pass.

It would be helpful if there was a way to see the failed output.
