Don't process events when print message in ctkConsole

If a refresh of the console widget is requested, then it should be done
directly in ctkConsole::printMessage or even better
ctkConsolePrivate::printText.
In any cases, processEvents() is disproportionate.QWidget::update() or
 QWidget::repaint() should be enough.
