[clang] Fix redirection behaviour for cached FileEntryRef
In 6a79e2ff1989b we changed Filemanager::getEntryRef() to return the
redirecting FileEntryRef instead of looking through the redirection.
This commit fixes the case when looking up a cached file path to also
return the redirecting FileEntryRef. This mainly affects the behaviour
of calling getNameAsRequested() on the resulting entry ref.
