remove AFS path from PathResolver search path

I think this is just meant as a safety backup in case the paths above don't exist, but it breaks when AFS is not available off-site (as searching that path will just hang).

Adding full-unit-tests, as I'm really not sure if this breaks anything. Though it may even break some unit tests that contain a printout of the search path and then require it to match the reference (which is probably a bad idea to check in a unit test).
