New messages are shown with a UI "hiccup" instead of a scroll down animation

## Steps to reproduce
1. Receive a message
2. Open the corresponding chat
3. The chat jumps down to show the latest message(s)

### Expected behaviour
The new messages should be shown with an animation, possibly scrolling down, or simply already be there when the chat is opened.

### Actual behaviour
The chat "jumps" down instantly, which is unpleasant to look at and very frequent. The same issue for messages under the "New messages" label has been solved https://github.com/nextcloud/talk-ios/issues/992
