Fixed an incorrectly repaired merge conflict from the previous revision of this branch.

Converted many calls to generic_fns.mol_res_spin.generate_spin_id() to generate_spin_id_unique().

This will allow many future bugs to be avoided, as the spin ID string is most often used to retrieve
spin containers. By using the generate_spin_id_unique() function, the returning of spin containers
will always be correct.

The generic_fns.mol_res_spin.generate_spin_id_unique() function now handles missing spin containers.

Previously if this function was used to generate a spin ID string of a spin not in the data store,
it would fail. Now it generates an ID by defaulting to generate_spin_id().
