Skins, like extensions, can register PHPUnit tests.
The testsuite interface in PHPUnit is designed to execute one run only,
so this should be based on the semantic entry of "skin jobs".
Changing the Jenkins job to run both doesn't work (only one value accepted).
Working around by running phpunit twice also seems wrong.
