[SPARK-4803] Remove duplicate RegisterReceiver message
- 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, RegisterReceiver message uses the same streamId and the
receiverInfo gets updated everytime
the message is processed at the `ReceiverTracker`, it makes sense to call
register receiver only after the
receiver is started.
