When cyclic garbage collection (gc) runs finalizers that resurrect unreachable objects, the current gc run ends, without collecting any cyclic trash. However, the statistics reported by ``collect()`` and ``get_stats()`` claimed that all cyclic trash found was collected, and that the resurrected objects were collected. Changed the stats to report that none were collected.
