[QLC+ 5][macOS] Save on exit doesn't block the exit process

[mcallegari]

Windows and Linux are OK, but on macOS the "save before exit" popup doesn't stop the application to quit.
Might be Qt related and (damnit) a special case to handle on macOS.

QTBUG submitted https://bugreports.qt.io/browse/QTBUG-72013

The QTBug is fixed since QT 5.14 :)

No it's not.
The fact they close a ticket doesn't mean they resolved it.
If you built QLC+ 5 before commenting, you would see yourself.
I did, on 5.14.2 and Cmd-Q doesn't prevent QLC+ from closing without asking first.

They say to use the quit signal so I tried also this:
connect(this->engine(), &QQmlEngine::quit, this, &App::slotClosing);
Doesn't work too. Qt 5.15.2.
