I believe that this realm always existed.Henry said on his own that there are many realms, endless possibilities. There are many versions of any world and anything could be real. Emma's wish was not to be the saviour, but other things changed to: Robin was young (maybe because something happend to his past), Neal was in that realm before not in the realm without magic, because maybe he never got there. So The Evil Queen didn't create a wish world for Emma, she wished for Emma not to be the saviour and the past didn't changed, she was just sent to a realm that she is not the saviour.

I don't have the answer if there was another Emma before, but i believe that my theory is correct
