Newer PHPUnit versions don't allow for non-existing directories in testsuites about github-actions-m2

@fredden That sounds like an uglier solution. @fooman his PR fixes this on a more fundamental level. I'm going to test this out in the upcoming days.

Is it just the directories that need to exist, or do they each need to contain files? Perhaps a mkdir -p would appease the new check.

I think we should be able to adjust this on the fly to make this useful across a range of different ways of adding tests. Just created a PR #66 which should loop over whatever we supply in phpunit.xml and remove any entries which don't exist.

The solution works for me. +1 for closing this.

In the mean time I'm also copying the same solution to unit tests as well.
