repo: remove now-unused changectx() method (API)
repo.changectx(x) was just a synonym for repo[x], so any extensions
that fail due to this commit should switch over to that form.

Test that branchheads cache is updated correctly when doing a strip in which
the parent of the ancestor node to be stripped does not become a head and also,
the parent of a node that is a child of the node stripped becomes a head (node
3). The code is now much simpler and we could just test a simpler scenario
We keep it the test this way in case new complexity is injected.
Create repo b:
$ hg init branch-heads
$ cd branch-heads
