- RefUpdate: Protect against null ObjectId in ReceiveCommand
RefUpdate's onRefOperation method is invoked by RefOperationValidators
for every registered RefOperationValidationListener.
If one of those listeners passes a RefReceivedEvent that contains an
instance of ReceiveCommand that was initialized with null old or
new ObjectId, this results in a NullPointerException when the ObjectId
is dereferenced to get the name.
Protect against such misbehaving validators by translating any null
instance to ObjectId.zeroId().
