Model selection in the dispersion auto-analysis is only performed if 2 or more models are present.

Excluding the 'R2eff' model, if only 0 or 1 models are optimised, then model selection is skipped
and a warning is given. This avoids tracebacks in the model_selection user function.

Fix for the Relax_disp.test_exp_fit system test.

Now this checks the fitting of exponential curves without using the auto-analysis - the
auto-analysis is an overkill.

The error when selecting a non-existent model using relax_disp.select_model is now more informative.

The spectrum.peak_intensities is now more robust when reading in a generic formatted file.

Firstly there is a check that the intensity column number has been supplied. And then there is a
checks that all relevant data could be extracted from each row of the file. This replaces traceback
errors with RelaxErrors explaining the problem if the user inputs bad data or forgets the intensity
column argument.
