context: translate FilteredIndex/LookupError at repo[changeid] (API)

This partially backs out ecd3f6909184. It seems layering violation for
repo[changeid] to raise storage-level exceptions transparently. Otherwise,
we would have to rewrite callers to catch all of them.

  try:
      repo[rev_or_node]
  except (error.RepoLookupError, error.FilteredIndexError,
          error.FilteredLookupError):
      pass

This would also fix filectx._changectx(), which catches FilteredRepoLookupError
to fall back to the unfiltered path.
