topic: wrap branchmap.read() as well (compatibility for hg <= 4.9)

In hg 5.0+ this logic lives in branchcache.load method, but in older versions
there's a module-level function that loads on-disk cache and returns a
branchcache object. Since we need the cache to have branch names in the FQBN
format, we need to wrap branchmap.load() and do the conversion there as well.
