[hibernate-dev] Mistake in the JUnit3 cleanup

Hi Hardy, sorry I screwed up both during review and setting up ci.hibernate.org : the code in Maven module _hibernate-search-performance_ isn't compiling anymore; could you extend your refactoring to this module please? This slipped in as the profile is disabled by default; I'm fixing the pull requests checker to verify this profile as well. I suspect I wanted to keep the PR checker quick and lean, but it doesn't take too long now. Cheers, Sanne
