discovery: avoid wrong detection of multiple branch heads (issue6256)
This fix the code using obsolescence markers to remove "to be obsoleted" heads
during the detection of new head creation from push. The code turned out to not
use the branch information at all. This lead changeset from different branch to
be detected as new head on unrelated branch.
The code fix is actually quite simple. New tests have been added to covers
these cases.

==================================== Testing head checking code: Case C-2 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category C: checking case were the branch is only partially obsoleted. TestCase 1: 2 changeset branch, only the head is rewritten .. old-state: .. .. * 2 changeset branch .. .. new-state: .. .. * 1 new changesets branches superceeding only the head of the old one .. * base of the old branch is still alive .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
