Fixes apache#352 ### Motivation apache#303 adds the flush callback to the last `OpSendMsg` instead of adding to the batch message container. However, `batchMessageAndSend` will create an `OpSendMsg` and add it to the `pendingMessagesQueue_`. https://github.com/apache/pulsar-client-cpp/blob/7bb94f45b917ed30b5302ac93ffa1f1942fc6313/lib/ProducerImpl.cc#L384-L389 In the code above, `pendingMessagesQueue_` could never be empty and the callback will be added again by `opSendMsg->addTrackerCallback`. The 1st time it's added in `createOpSendMsg` or `createOpSendMsgs` called by `batchMessageAndSend`. ### Motivation Add the callback to the last `OpSendMsg only when the batch message container is empty. In `testFlushBatch`, replace the `flush` call with the `flushAsync` call and verify the callback is only called once after it's completed.

Motivation
When sendAsync batch messages and then flush() and close(), found that the callback of message is ResultAlreadyClosed but not Ok.
The root is if there is no batch messages remain in BatchMessageContainer when do flush, the flush callback directly return Ok. Instead, it should return Ok until the lastSendOpFuture complete.
