mq: update bookmarks during qrefresh

Bookmarks are updated during qpop and qpush, but they are not updated
during qrefresh. This behaviour makes it hard to work on an evolving
changeset at the head of a branch. qrefresh should update all bookmarks
that point to the refreshed commit with the new nodeid.
