localrepo: introduce method for explicit branch cache update
Currently, localrepo.branchtags() is called in two locations to update the
_branchcache dict, however branchtags() itself does not update anything, it
calls branchmap() to do so. This change introduces a new updatebranchcache()
method that is used by both branchmap() and the calls to update the cache.
