Handle data-not-found for MoC devices
If a print we have stored locally is not available in device anymore, we need to cleanup the local database.
To do this rely on libfprint data-not-found error, and if we get that during identification or verification, delete the selected print (in case of verification) or remove the prints not listed anymore by the device (in case of identification).
