GadgetBridge reconnection does not work if Whitelist enabled

@Gordon:

1. Resetted all settings to default. Connecting was no problem. Reconnecting (deactivate/reactivate Bluetooth on phone) also works.
   
2. Activated passcode. This also connects fine when providing the correct code. Reconnecting also works.
   
3. Added the device to whitelist. Reconnecting works as long as I don't leave the settings app. Even when switching Bluetooth off and on again on my phone. When I leave settings, reconnecting does not work anymore.
   
   

When doing "add device" in the settings and then reconnecting (by switching Bluetooth on the phone off, then on and then reconnect GadgetBride) multiple times, I get different device addresses. So it really seems as if the phone changes its address every time Bluetooth is switched off and on again. Anyhow, it's strange that it's still possible to reconnect with (presumably) different address as long as I do not leave the settings app.
