mupp: fix crash in PmuppGui::getValues plotting a variable.

getValues()/getErrors() return a std::vector by value, but the QVector was
built from begin() of one call and end() of a second call -> iterators into
two distinct temporaries -> UB and a segfault in getValues(). Bind the result
to a single local before taking begin()/end(). Same in getPosErr/getNegErr.

This surfaced reliably when plotting a <python>-generated variable added via
the GUI (the script path was unaffected as it reads getValues() only once).

Also fix check() to validate the actually selected collections
(GetCollection(idx[i]) instead of GetCollection(i)).

-# musrfit - muSR and beta-NMR data analysis package #
-
-### Contents ###
-
-This is a data analysis package to analyze time differential muSR and beta-NMR data.
-Currently it allows the following:
-
-* set up most commonly used fitting functions for muSR and beta-NMR
-* fit data, including global fits
-* show the fit results and the residuals
-* show the Fourier transform of the data
-* easily extract the fit parameters and import in other programs (gnuplot, qtiplot/origin, ...)
-* generate input fitting files for follow-up runs
-* generate global input fitting files based on a single run template
-* implement more sophisticated user functions
-  (e.g. GL vortex lattice, Meissner screening including low-energy muon stopping profiles)
-
-### Currently supported platforms: ###
-
-* Linux
-* Mac OS X
-* Windows 10 1809 or newer - current state is for the commited ones
-* Web based implementation - http://musruser.psi.ch/cgi-bin/musrfit.cgi
