Add handling a local lock operation error to door-lock-server
Browse files Browse the repository at this point in the history
The current implementation of the door-lock server supports emitting
the LockOperationEvent only if the credential has been provided remotely.
In case we use a custom handling lock credential in the application
code the event is emitted only on the correct credential, but we also
need a mechanism that allows the door lock server to handle a lock
operation error when the wrong credential has been provided.

Added handling local lock operation error to emit LockOperationEvent
and call HandleWrongCodeEntry.
