topic: bring back oldbranchmap context manager for hg 4.9

This is only needed in Mercurial 4.9 because branchcache class there tries to
use super() in its __init__() and it results in an infinite recursion because
we also implement __init__() with super() in _topiccache and then replace the
original branchmap.branchcache class with our own.

At least there are now compatibility comments to help remove this hack ASAP.
