Salvager: Don't use garbage vnodes when Testing
If Testing is true, and the salvage wants to repair the '.' file,
then it will end up using a garbage value as the location of the
repaired file (vnodeNumber gets set to fid.Vnode, but fid.Vnode is
uninitialised)
Fix this by making it behave as if no repair is necessary when running
in Testing mode. It's unclear that this is entirely the correct answer,
but it's definitely better than the current behaviour.
