bundlerepo: properly handle hidden linkrev in filelog (issue4945)

The bundlerepository have to do some special magic to handle linkrev of the
bundlerepo filerev. That logic was done from a repoview and obsolescence marker
affecting bundled changeset could lead to a crash. We now ensure we operate on
unfiltered repository.
