* Remove room list range deduplication and allow subscribing to rooms when then update to come into the visible range.
* Fixes#3088 - Update subscriptions if visible range rooms change without the range itself changing
- we switched from range based subscribing with duplicate suppression to id based, but ids can change without ranges changing
- the all rooms list fetches at least 1 event per rooms and can cause rooms to come in and out of the visible range without user interaction
