Well, Snow and Charming prevent their baby from going back to the past so Cora never meets Johnathan; so she never gets the chance to "worm her way into the dregs of loyalty" with either Leopold or Henry. Regina is never born as a result so no curse is cast. That would defeat the whole purpose, of ever making this show. Besides, it is out-of-character for Mary Margaret and David to do something like that. They gave up Emma for the greater good, they would easily do the same with their son.
