Fix for bug #21763 (https://gna.org/bugs/?21763).
This is the problem of the chi2 value not being visible in the parameter list of the grace.write and value.write user functions in the GUI.
The problem was that when asking for the parameter name list, the minimisation parameters were not being asked for.
