bluetooth: fixes for NMManager bluetooth device handling

- Re-query the BlueZ manager when connection, or connections are
  added
- Don't assert when a new BT device is created
- Fix the connection bdaddr and device bdaddr comparison, we
  were comparing a byte array with a string
- Simplify bluez_manager_bdaddr_has_connection()
