Error when specifying port name as origin for move operation

[tvt173]

Hi,
Previously we were able to supply a port name on the component reference as an origin for a move operation. This is now broken because of the renaming of midpoint to center. The problem is that str also has an attribute called center. I would recommend we check if the origin is a string first to catch this case.

gdsfactory/gdsfactory/component_reference.py

Line 350 in ecac4cf

if hasattr(origin, "center"):

Hi Troy, can you provide some code to reproduce the error? That way we can add a test for it:)
