Motivation
In c++ consumer, when receiving batched messages, the acknowledgment tracker is incorrectly trying remove the messageId from the last message in batch being acked from the
sendList. In that list, the message ids being inserted are always the ones from the batch, not the individual messages.The result of this is that the sendList keeps growing, using memory and making the linear search to skyrocket in cpu/time.
Note: this is just a quick fix to address the most pressing issue. A better fix will be to implement an equivalent of #1424.
