commit 791d342a98d0f0b4189913a5ea61547964d095c8

Fix logic of command for sendError (#622)
### Motivation
As shown in the figure above, the `ServerError` returned by the broker is
`UnknownError` when the client receives it. In fact, we handled the wrong
command here. Here we should deal with `CommandSendError` instead of
`CommandError`. Correspondingly, we should deal with the `listener` map used to
cache the producer instead of the corresponding `pendingRequest` map.
