shelve: drop unnecessary backup of dirstate for phase-based case Regular shelve has a hack using an uncommitted transaction that's then aborted at the end of the operation. It preserves the dirstate across the abort, however, by saving a backup copy of it. Phase-based shelve instead commits the transaction, so the hack shouldn't be necessary there.
