      The following code:

         collection.aggregate(pipeline, AggregationOptions.builder()
                                           .batchSize(1)
                                           .build())

      will send nToReturn of -1 to OP_GET_MORE when fetching the second batch of documents.

      On server 3.4, this results in a uassert:

      AssertionException handling request, closing client connection: 34419 Invalid ntoreturn for OP_GET_MORE: -1

      The driver should be fixed so that it sends nToReturn of 1 instead.
