I suspect they would just say Mirri maz daur was either lying to hurt Dany even worse, or just mistaken, or maybe they will make it be due to some kind of LoL miracle or something like that...I'm still just not buying into it yet, but on the other hand..it sure feels like they are foreshadowing something down that path. I feel however that even if it true, it will just be another way to take a dump on the fans, and rip our hearts out, something along the lines of Jon dying fighting the Night King, but stopping him, and then Dany dying in childbirth, leaving a parentless child
