Merge 1d7846b0f9 into fafd11f809

This patch fixes a typo in `/rooms/{roomId}/relations/{eventId}`. The
specification says about the `from` request query parameter:

> The pagination token to start returning results from. If not supplied,
> results start at the most recent topological event known to the
> server.
>
> Can be a `next_batch` or `prev_batch` token from a previous call,
> or a returned `start` token from `/messages`, or a `next_batch` token
> from `/sync`.

The last part is wrong. It should be:

> … or a `prev_batch` token from `/sync`.
