Bump the SDK and handle breaking changes on timeline diffing

- avoid race conditions between when a timeline listener starts publishing to the `updatePublisher` and when they are consumed (and in which order)
- subscribe to the timeline directly in the TimelineProvider and correctly process updates serially
- update the AutoUpdatingRoomTimelineProviderMock to use an SDK TimlineMock and listener to publish updates
