pushbookmark: do not attempt to update bookmarks if the push failed (BC) Before this patch, there was always an attempt to update bookmark even if prior steps of the push failed. I cannot see a good semantic reason to do so. We disable this possibility to simplify the push flow with bundle2. Bookmarks will be included in the bundle and fail with other steps.
