run-webkit-tests splits the platform test path at any "-" character, including those in paths that are above the WebKit checkout directory. This causes tests to be searched for in both "WebKit" and "WebKit-fb" if running the WebKit-fb tests when you've got a folder setup like this:
~/WebKit/ -- WebKit trunk checkout
~/WebKit-fb/ -- WebKit feature-branch checkout
