The show'd mantra is "If we tell you something that means it's true, it doesn't matter if it contradicts previous rules we established or if we show ON SCREEN something completely different", so when they constantly say that Emma is The Savior that means she is even though someone else saves everyone. It is kind of like how it is said that Hook is a hero even though he really isn't. Some fans take that bait, some are smarter than that.

IMO, it is a joke. It's as people would have called Buffy The Slayer even if Willow had been the one to save everyone.
