Use local room list sorting from Rust. (#2978)

* Switch to the new local room list sorting API

* Get rid of the RoomSummary enum, replace it by the inner RoomSummaryDetails

* And finally, rename RoomSummaryDetails to RoomSummary

* Fix a bunch of warnings

* Small tidy up post rebase/review.

- Remove unused invalidated property.
- Rename some RoomSummary instances to summary instead of details.
- Fix tests with missing roomListItem's.

* Update snapshots
