> The ReceiverTracker receivers `RegisterReceiver` messages two times
>      1) When the actor at `ReceiverSupervisorImpl`'s preStart is invoked
>      2) After the receiver is started at the executor `onReceiverStart()` at `ReceiverSupervisorImpl`
> Though the 'RegisterReceiver' message uses the same streamId and the receiverInfo gets updated every time the message is processed at the `ReceiverTracker`, it makes sense to call register receiver only after the
> receiver is started.
> or, am I missing something here?
