localrepo: do not update bookmarks in addchangegroup
We want to update the current bookmark to the most recent revision on
current branch unless there is a remote bookmark that points to
a different descendant. Addchangegroup is called before we can check for
remote bookmarks.
We don't update the bookmark in addchangegroup anymore to allow proper updating
of bookmarks in pull.
