Issue Description
按照博客文章 https://blog.botframework.com/2017/06/19/Load-Testing-A-Bot/对机器人进行负载测试，我创建了一个"接收器"服务以向机器人发送消息。由于它将其用作消息中的 serviceUrl，因此机器人也会出于其他目的与接收器服务通信。 我可以发布到机器人，但是在机器人回话时，它会发送一条类型为"event""Debug"的消息，该消息在地址中没有对话对象，从而导致引发异常。
预期行为
机器人将活动发送回接收器服务
实际结果
发送活动类型"messge"和"typeping"后，调试事件活动会引发异常：
TypeError: Cannot read property 'id' of undefined

发现问题，调用机器人终结点时，活动必须提供对话 ID。这在博客文章中没有具体说明。通过向正在发布的活动添加conversation: { id: <id> }，它可以工作
