All/everyone/stream mentions don't show up in mentions narrow

@all, @everyone and @stream mentions don't seem to appear in the mentions narrow.

I would recommend against testing the anomaly on any stream with a high subscriber count and would recommend using the zulip dev server.

Also see #zulip-terminal>Bug: "all" mentions for original report and possible future discussion.

@neiljp Thanks for mentioning the stream and identifying the issue. 👍
