When an unseen message is opened, we flag it as seen. So far, so good.
But in this code path we returned early from the `fetchMessage`
function, meaning that `this.loading` remained set to `true` and the
loading spinner never vanished.

My guess is that this is a leftover from the migration from promises to
async-await.

On page load we have a lot of concurrent operations going on. This
includes:

1) Loading the list of envelopes
2) Loading the contents of the thread

Both of these might fetch the envelope/thread to be shown. Now, there is
some more logic going on that stores the thread of an envelope.

In the unlucky case, things followed this pattern

1) The envelope is fetched
2) The thread list is fetched and stored to the envelope
3) The envelope list is fetched and the envelope is added again,
   overwriting the other one
4) The thread list was thus empty -> the current message thread vanished

If the envelope is already known, it will be re-used. Thus this won't
happen on later navigation but just right after the page load.

What we show there (now) is the thread, not just one message.
