QBluetoothSocket::errorOccured is not emitted in certain circumstances

One circumstance is when trying to connect to a device whose Bluetooth is turned off. For example, on Ubuntu QBluetoothSocket::errorOccured should be triggered and tell us
"Cannot connect to remote profile". But nothing happens on macOS.

Also from original reporter:
"In Windows and Android, the signal errorOccurred is properly emitted when, for example, the device I am connected to is shut down. However, this signal is not emitted in MacOs when performing the same actions to force the error".
