Stop scanning after successful pairing

Description
Some Bluetooth adapters seem not to like scanning at the same time as they're handling audio, resulting in loads of quality problems, or even drop offs.
To work-around this hardware, we should probably stop scanning during pairing and initial connection. If any of those fail, we'd restart scanning. If everything worked properly, we would require a user action to continue scanning and eventually pair other devices.
