Fix for bug #21591 (https://gna.org/bugs/?21591), the complete failure of the NOE analysis.

This bug was reported by Martin Ballaschk (https://gna.org/users/mab).

The issue was introduced in the fix for bug #21562 (https://gna.org/bugs/?21562). The problem is
that the overfit_deselect() method was deselecting all spins with two data points or less rather
than one or less.

Improvements for the steady-state NOE analysis overfit_deselect() method.

The spin deselection which occurs at the start of the calc user function call, used to calculate the
NOE, is now clearer. Each deselection condition is now explained in detail and the text is now far
more informative.

In addition, the special condition of all spins being deselected is now caught. If this happens, a
RelaxError is raised to prevent the user from going forwards. This should remove confusion as to
why the output file is empty.
