ecm_create_qm_loader: fix to listen just to language change of app instance

QCoreApplication processes also the events for all objects, thus including
widgets. So the event filter would also see all the LanguageChange event
notification for each of the widgets when the event itself is passed from
the toplevel widgets to all the child widgets.
