branches: avoid unnecessary changectx.branch() calls
This requires reading from the changelog, which can be costly over NFS.
Note that this does not totally remove reading from the changelog; we

removed in a later patch.
Running hg branches on the PyPy repo (with 996) over a busy NFS server,
before this change:
