tst_QApplication: Remove test windowsCommandLine().

According to history, the test was supposed to verify
the correct parsing of the command line on Windows by the qWinCmdLine()
function in corelib. It did not test anything since the test
application printed out argv[1] instead of
QCoreApplication::arguments()[1]. Since qWinCmdLine() has been replaced
by the WinAPI CommandLineToArgvW(), the test no longer makes sense
and also starts to fail then warnings are printed to the error output.
