Connect quit() and exit() signals with queued connections

Class QQmlApplicationEngine connects QQmlApplicationEngine::quit()
signal to QCoreApplication::quit() and QQmlApplicationEngine::exit()
signal to QCoreApplication::exit(), but it does so with AutoConnection.
This causes in some circumstances problems, which are described in Qt
documentation (see QCoreApplication::exit()). This change modifies type
of connections to queued connections.

[ChangeLog][QtQml][QQmlApplicationEngine] QQmlApplicationEngine
connects quit() and exit() signals with queued connections to avoid
problems with AutoConnection, when connecting to QCoreApplication
slots.
