Genies cannot change the past via a wish. Changing the past was not possible until Zelena's time travel spell.

Zelena: I'm going to change the past. Rumple: No. Time travel spells have been written since the dawn of the dark arts but never cast. It's against the fundamental laws of magic. Zelena: Magic doesn't fail. People fail. Laws only exist until they're broken by someone... superior. Rumple: You? You've deciphered the laws of time travel.
