[WIP] Message List Data Source Decorator

[nuno-vieira]

🔗 Issue Links

N/A

🎯 Goal

Possibility of overriding the data source in the message list.

Potential edge cages: 1- If all messages from the first page are removed (unlikely), loading more messages is impossible. 2- If from the first 25 messages, only 1 or 2 are filtered, then it will feel like there are no more pages, but there is. 3- The preview message in the CHannel list might not be in sync if last message from the message list is removed

@nuno-vieira if we would use cursor for pagination, would it solve these pagination issues? (but I guess it is a bit of a change as well)
