bookmarks: allow push -B to create a new remote head (issue2372) Push is currently allowed to create a new head if there is a remote bookmark that will be updated to point to the new head. If the bookmark is not known remotely then push aborts, even if a -B argument is about to push the bookmark. This change allows push to continue in this case. This does not require a wireproto force.
