Websocket chat example prone to DOS.

[illisit]

If I use the web socket chat example verbatim.
and then open a web-socket using curl.
curl --include --no-buffer --header "Connection: Upgrade" --header "Upgrade: websocket" --header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" --header "Sec-WebSocket-Version: 13" http://127.0.0.1:3030/chat
The server becomes completely unresponsive, and the logs spam with
DEBUG warp::filters::ws > websocket poll error: Trying to work with closed connection
indefinitely. I'm not exactly sure why this occurs. Something with curl opening and closing the connection too quickly perhaps?

@Bohdan77 if you solved this issue, could you tell us how?

@asonix Sorry I didn't think the fix was worth responding, as it's just an example.

The problem is here.
If you simply change the continue to a break, the issue is eliminated.
I'm not sure if there could be errors that should be ignored, instead of closing, however.
