A STREAM_MUTATION_DONE message will signal the receiver that the sender
has completed the sending of streams mutations. When the receiver finds
it has zero task to send and zero task to receive, it will finish the
stream_session, and in turn finish the stream_plan if all the
stream_sessions are finished. We should call receive_task_completed only
after the flush finishes so that when stream_plan is finshed all the
data is on disk.
