No, because the wish was for Emma not to be the savior, not for Regina not to cast the curse.

Anything leading to Emma becoming the Savior must have changed (which possibly includes Rumple's motives) And Regina casting the curse led to her becoming the saviour. From what we saw from that episode, it was still Rumple who tried to get Regina to cast the curse.
