Subscribe to RoomListItems in the visible range

[jmartinesp]

This ensures the room list items always have updated info.

Content

• Subscribe to RoomListItems in the visible range so we always have updated info for them. This also helps preload the data rendered when you open one of those rooms.

Motivation and context

Fixes a limitation introduced by the client side sorting since we no longer use SlidingSync's visible_rooms and only fetch the latest event of all the room list items (which, if it's a state event, won't be displayed in the room list).

Tests

• Clear cache / log out and in with your account.
• Once you're in the room list again you'll see the first few items may have incomplete data.
• Shortly after, the UI should change and reflect the latest info.
• If you scroll, older items will also lazily load this data.
• No rooms should be displayed without a latest event. If there is one, it's probably because its latest message-like event is not in the latest 20 loaded events.
