prune: fix pruning w/ bookmarks and inhibit
Previously prune would create the obsolesence markers, then try to fix up the
bookmarks. With inhibit enabled, the act of closing a transaction for the
bookmark step caused it to unhide commits that were trying to be pruned.
The fix is to put the whole thing in a transaction.
