Bug fix for the Relax_data_store._back_compat_hook() function for the interatomic data support.

The calls to functions of the generic_fns package need to operate on a non-current data pipe.

A number of the generic_fns.mol_res_spin functions now accept the pipe argument.

These include name_spin(), set_spin_element(), and set_spin_isotope() and this allows the functions
to operate on any data pipe.

The dipole_pair.define user function backend now can handle the pipe argument.

This allows it to operate on an alternative data pipe.
