[phenixbb] Bug squash request

Dear Phenix-developers,

I've noticed a slightly annoying "feature" when using a reference model to help in refinement of  low-resolution structures.

phenix.refine seems to take it's crystal parameters and space-group from whichever PDB was loaded last, even after setting one PDB as the "reference model" and the other as the "Input model".

When running phenix.refine it gives you a nice error message telling you that the space group information is incorrect, and that you may have used the reference model's parameters by mistake…

But surely, it should just (by default) only take (check?) the cell parameters and space group information from the "Input PDB"?

With thanks,
