Modified the metal_pos_opt.py N-state model system test script to catch yet another bug.

Bug fixes for the _opt_uses_pcs() and _opt_uses_rdc() N-state model methods.

These now check that the populations are optimised as well.

Improved the checks of the metal_pos_opt.py N-state model system test script.

Modified the metal_pos_opt.py N-state model system test script to demonstrate some failures.

This change also caught the bug fixed in r18282.

Bug fix for the N-state model Hessian d2func_standard() method.

An index variable name was incorrect causing the population model to fail with Newton optimisation.

Modified the populations.py N-state model system test script to better test optimisation.

The probability of the 2nd state has been slightly shifted to make sure the original value can be
found.

Improved the comments in the _disassemble_param_vector() N-state model method.

Simplified the parameter unpacking in the func_standard() N-state model target function.

BFGS optimisation is now being used for the N_state_model.test_mc_sim_failure system test.

This is to have better test coverage of the paramagnetic centre position optimisation gradient code
paths.
