Fixing crash with -auto_setup_metals when poses were resized
Correcting issue that lead to crashes whenever -auto_setup_metals was used with a pose that was subsequently resized. Since NamedAtomPairConstraint and NamedAngleConstraint didn't implement a remap_resid() function, the parent class (AtomPairConstraint or AngleConstraint) function was called, resulting in the NamedAtomPairConstraint being replaced with an AtomPairConstraint, or the NamedAngleConstraint being replaced with an AngleConstraint, with atom IDs set to zero.
