Description:

The livechat agent in a conversation shall be pictured (literally) in the livechat-header of the client. This is not the case with guest-pool configured.

Steps to reproduce:

1. Configure livechat with guest pool
2. Open a client session
3. Send a message from the client
4. Pick the inquiry from the queue

Expected behavior:

The agent joined shall be shown in the client header

Actual behavior:

Only, once the client refreshed the browser, the agent's data is shown

Server Setup Information:

• Version of Rocket.Chat Server: 0.70.4 && develop

Additional context

I have done quite some intense research on this issue.
I debugged / traced, that

• the event agentData is properly emitted
• the autorun in the client (_livechat.js) runs once on initialization, but no more once the agent joins
• the streamer event handler function (this.stream.on) is never executed
• the room ID which is used as the key for the streamer is the same for the emitted and listened-on-event

I added a patch with all logs and some other helpless tries I added, for convenience if it may help

I have seen that the streamer has undergone quite some changes on Oct. 24, so I at least can imagine that it may be an issue in the lib.
