discovery: properly filter changeset in 'peer.known' (issue4982)

The 'peer.known' call (handled at the repository level) was applying its own
manual filtering (looking at phases) instead of relying on the repoview
mechanism. This led to the discovery finding more "common" node that
'getbundle' was willing to recognised. From there, bad things happen, issue4982
is a symptom of it. While situations like described in issue4982 can still
happen because of race conditions, fixing 'peer.known' is important for
consistency in all cases.

We update the code to use 'repoview' filtering. This lead to small changes in
the tests for exchanging obsolescence marker because the discovery yields
different results.

The test affected in 'test-obsolete-changeset-exchange.t' is a test for
issue4982 getting back to its expected state.

 note that the bumped changeset (5:5601fb93a350) is not a direct successor of
 the public changeset
