DeviceCommunicationService: catch uncaught exceptions from handleActions

Exceptions raised while handling actions in the device's support class
may result in the DeviceCommunicationService crashing as a whole and not
being started again until the user forces GB to make a connection by
pressing the device from the list.

This change is made, because Xiaomi devices make use of proto2 messages,
where optional fields cannot be set to null values as that will make it
throw NPEs.
