Aircraft ICAO code of own model is wrong

Although the reverse lookup of a model is correct, it's aircraft ICAO code is wrong

Issues found

* in the driver the ICAO code is permanently overridden -> commented out
* there are two contexts, own aircraft and simulator, but only one uses reverse lookup -> now both
* using Qt::QueuedConnection for context -> GUI
