Use after free due to card's reason effect being reset

[edo9300]

First case of this issue was encountered on a call to Duel.ReturnToField where the effect that banished the card the first time had been reset. The scenario was Time Magic Hammer banishing a monster, then that same time magic hammer leaving the field and thus the effect that banished the card (and thus was set as the card's reason effect) was reset
