Evangelos Ribeiro Tzaras 0e6d5d9745 record-store: Don't crash on unexpected call state changes ...

It has been reported that the BM818 sometimes unexpectedly
changes the call state from "active" back to "ringing-in"
(as reported by ModemManager) shortly after accepting an incoming call.

ModemManager[734]: <info>  [modem1/call1] user request to accept call
ModemManager[734]: <info>  [modem1/call1] call is accepted
ModemManager[734]: <info>  [modem1/call1] call state changed: ringing-in -> active (accepted)
ModemManager[734]: <info>  [modem1/call1] call state changed: active -> ringing-in (unknown)

This leads to a failed assertion and program termination.
Instead of crashing raising a critical warning is more appropriate
and may allow the user to pick up the call after all.

Closes: #547
