The UI does not remove the preference

The LE audio structure have two or more devices, it use CSIP to combine
them with the groupId. It breaks the UI structure, since the UI use the
map to save relationship between the bluetoothDevice and preference.
There are two or more devices using the same UI, it causes UI show the
wrong preference when CSIP do switching of device.
Remove the unuse device when UI refreshing.
