Bug fix in noproj to remove persistent temporary lbl file

In testing the noproj app for upcoming modifications, Sarah Sutton (@artmathgirl) discovered that there was still a persistent temporary match file (extension lbl; e.g. matchXXXX.lbl) remaining after running noproj. This results from not closing the match cube after returning from the call to cam2cam (and sadly, I didn't catch it) e.g. ...

Code snippet from noproj.cpp (~line 375)... // And run cam2cam to apply the transformation QVector args = {"to=" + ui.GetCubeName("TO"), "INTERP=" + ui.GetString("INTERP")}; UserInterface cam2camUI(FileName("$ISISROOT/bin/xml/cam2cam.xml").expanded(), args); Cube matchCube; matchCube.open(matchCubeFile.expanded(), "rw"); cam2cam(icube, &matchCube, cam2camUI); matchCube.close(); THE MISSING LINE

Description

Added the line to close the matchCube in noproj.cpp.

How Has This Been Validated?

noproj tests were rerun, all pass on Mac except for DefaultCube.FunctionalTestNoprojFromUser.

Note that this test seems to be failing in the current ISIS dev but was passing after the last two noproj PRs.

There are very subtle differences in hist->Average() hist->Sum()

Having some trouble explaining that, but sure that this isn't a result of this bug fix.
