Marie Janssen 6a383a7d32 Bluetooth: prevent enabling BLE in airplane mode
Enabling BLE in airplane mode puts BluetoothManagerService in an
unexpected state which causes Bluetooth to be on when airplane mode
is disabled.

Also fixes a bug where a crash of a BLE client would trigger a restart
into ON mode.
