Fix to not show mic input notification when communication device is other bluetooth device

Root Cause: We use getAvailableCommunicationDevices to show mic input notification, but did not
consider the case that other BT (car in this case) will coexist with hearing device.

Solution: Change to listen to the CommunicationDeviceChanged to show mic input notification when
communication device for now is hearing device.
