narrow rangenotancestor to exclude target heads already present

Fixed regression in new revisioning traversal where "alembic downgrade
base" would fail if the database itself were clean and unversioned;
additionally repairs the case where downgrade would fail if attempting
to downgrade to the current head that is already present.
