Deleting QQmlApplicationEngine with inactive InsightTracker crashes

The QInsighttracker is instanciated in the C++ Part of the Application. The descission to activate it is done on start up.

The QML-Part will always call the sendScreenView and sendClickEvent functions, which are correctly ignored if the InsightTracker is disabled.

Upon closing the application the QQmlApplicationEngine is beeing deleted which will cause an access violation within the deiinit function of the Insighttracker.

If the Insighttracker gets activated directly before deleting the QQmlApplicationEngine or if it is running in general. no error occurs
