Resolve Behat test issues on Travis CI

[arithmetric]

Behat tests fail on Travis CI with the following error:

Fatal error: Cannot inherit previously-inherited constant BEFORE in /home/travis/build/phase2/grunt-drupal-tasks/test/working_copy/vendor/drupal/drupal-extension/src/Drupal/DrupalExtension/Hook/Scope/BeforeUserCreateScope.php on line 13

For example, see: https://travis-ci.org/phase2/grunt-drupal-tasks/builds/45110439

The tests pass on a local env with similar configuration (PHP 5.4.30).

This may be the same issue as #81

Tests are passing locally for me using php 5.5.19.

Some links:

• https://stackoverflow.com/questions/16097973/marker-constant-override-symfony2-error
• Cannot inherit previously-inherited or override constant LEVEL_TOP from interface Swift_Mime_Message swiftmailer/swiftmailer#477
• https://bugs.php.net/bug.php?id=59101

the common theme seems to be that this is APC related (but the linked bug indicates it was fixed in 2010).

Thanks for looking into this @jhedstrom.

I ran a few tests on Travis to follow up on this:

• I added the PHP 5.5 env, but still saw the PHP error: https://travis-ci.org/phase2/grunt-drupal-tasks/builds/47274633
• I ran a test to get the output from php -i and see that the APC extension is not enabled: https://travis-ci.org/phase2/grunt-drupal-tasks/builds/47276583
• This includes the output from pecl list and ls -lR ~/.phpenv: https://travis-ci.org/phase2/grunt-drupal-tasks/builds/47277906

It looks like 5.4 and 5.5 use opcache. Sadly, neither opcache nor XDebug appear to be the issue - I've disabled both in that branch and our tests still fail.

It also fails in a container-based build with opcache and XDebug removed. (I had to change netstat -an to a curl test.)

I bet this has to do with ZTS. No major distro ships packages with ZTS on, but Travis does for some reason.

This error is no longer present on Travis CI tests. 😃

The first successful pass seems to have happened here: https://travis-ci.org/phase2/grunt-drupal-tasks/jobs/67241663

So, this might have been fixed by #178.
