Foldit: Fix crash with mixed disulfides.
We were getting a fair number of crashes due to 'unknown atom_name: SG in residue CYS'.
This looks to be due to a location in src/interactive/util/ReferencePoseInfo.cc
which may be crashing when it gets a pose with mixed centroid/fullatom residue types.
Fix this by skipping the detection in cases where we have mixed modes.
