Fix T38265: transferring vertex weights from an object with modifiers not working.

It was using the modified mesh for the vertex coordinates, and the unmodified mesh
for the vertex weights, which can't work and crashed in some cases, now it used the
modified mesh for both.

Perhaps an option should be added to indicate if you want to transfer from the
unmodified mesh or transfer to the modified mesh, but I think this fix makes it
works as intended when this was implemented.
