pull: deal with locally filtered changeset passed into --rev

Nowadays, it is possible to explicitly pull a remote revision that end up being
hidden locally (eg: obsoleted locally). However before this patch, some
internal processing where crashing trying to resolve a filtered revision.

Without this patches, the pull output result a confusing output:

  $ hg pull ../repo-Bob --rev 956063ac4557
  pulling from ../repo-Bob
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 0 changes to 2 files (+1 heads)
  (2 other changesets obsolete on arrival)
  abort: 00changelog.i@956063ac4557828781733b2d5677a351ce856f59: filtered node!
