Fix for correctly enabling PAN profile in Settings

Update the connected profile list in CachedBluetoothDevice correctly
if a PANU-NAP connection is already existing but the onUuidChanged()
callback doesnt contain the PANU UUID in SDP inquiry. Now, the
DeviceProfileSettings screens displays valid 'Internet connection
sharing' option when connected as a NAP to remote PANU.
