协程 http 客户端响应，解析错误，body 包含了 header

### 问题描述

使用了 hyperf/guzzle 协程 handler 替换了 guzzle 的默认 handler（由 swoole 官方的 http 协程客户端实现），偶发一些情况 body 包含了头部信息，例如（这是 body）

`HTTP/1.1 200 OK
Date: Tue, 28 Apr 2020 11:04:14 GMT
Content-Type: application/json; charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Allow-Origin: *

1d
{"code":0,"msg":"","data":""}
0

通过 debug 发现原始的 swoole http client 已经解析错误，也就是说与 hyperf 无关：

`["statusCode"]=>
  int(100)
  ["headers"]=>
  NULL
  ["set_cookie_headers"]=>
  NULL
  ["cookies"]=>
  NULL
  ["body"]=>
  string(253) "HTTP/1.1 200 OK
Date: Tue, 28 Apr 2020 11:04:14 GMT
Content-Type: application/json; charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Allow-Origin: *

1d
{"code":0,"msg":"","data":""}
0

"
}`

### 相关代码
恕不能提供代码，参数和服务器都是敏感信息。我能确认的是在非协程环境是可以正常请求的。并且触发 bug 和参数关系很大，因为我们处理几十万请求，偶尔出现十几个异常的情况，异常情况单独在新进程和协程执行能复现。

### 你期待的结果是什么？实际看到的错误信息又是什么？

期待 header 内容不要被解析到 body，body 能正常就好。
