* refactor: convert RoomViewStore from flux Store to standard EventEmitter

Parts of a series of experimental changes to improve the design of stores.

* Use a gen5 store for RoomViewStore for now due to lock handling

* Revert "Use a gen5 store for RoomViewStore for now due to lock handling"

This reverts commit 1076af071d997d87b8ae0b0dcddfd1ae428665af.

* Add untilEmission and tweak untilDispatch; use it in RoomViewStore

* Add more RVS tests; remove custom room ID listener code and use EventEmitter

* Better comments

* Null guard `dis` as tests mock out `defaultDispatcher`

* Additional tests
