Convert more promise-based tests to async/await

- Use async/await instead of promises.
- Use different room jids (to try and see whether this fixes heisenbugs on travis)

updates #1209

fixes #1209

updates #1242

- No need for the `edited` event.
- Also, don't add load animation for MAM corrections

updates #1228

So that we first render dynamic content (e.g. images) before inserting
it into the chat.

Also, add the `show_images_inline` setting (which is the cause of this
whole change).

Updated tests to handle this new change and start using async/await
instead of promise callbacks.
