Delete QQmlApplicationEngine on application exit
Due to the API limitations, we have to ensure that the engine is deleted before other parts of the application is deleted. Otherwise exposing objects using setInitialProperties() or setContextProperty() for example will cause warnings to be printed. It is a good practice to always delete the engine manually so all the code should be consistent.
