Steps to repro:

1. On a vanilla instance with a new user, start to compose your first message.

2. The `education.new_topic` composer message will appear. Dismiss it.

3. Write until the draft process is triggered and the draft saves.

4. Refresh the page. The composer will re-open with your draft.

5. An exception will be thrown. [`_findMessages`](https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/components/composer-messages.js.es6#L157) attempts to add the welcome message to `queuedForTyping`, which is `null` at the time it is assigned.

The issue is with the sequence of reseting `queuedForTyping` and initialising the async `find` for composer messages, see the `console.log` in the screenshot.

One simple fix is to move the `queuedForTyping` assignment inside the `then` block of the composer-messages lookup, however I think there’s still race conditions with that solution. Nevertheless, that’s all I have time for right now…

PR seems to work fine, so I am merging it in.
