[EGIT PATCH 5/5] Correct getRepositoryMapping callers to use any IResource

["Shawn O. Pearce" <spearce@spearce.org>]

We really need to use the exact resource we want a mapping for, even
if that is an IFile, because the file may be in a different repository
than the project it is contained in.  This can happen due to linked
resources, or due to submodules.  Either way the mapping cannot be
driven by the project.
