Wrong MXRoomSummary properties from `MXSession.roomSummary(withRoomId: String)`

### Steps to reproduce

1. Leave a room or a space

### Outcome

#### What did you expect?

After leaving a room `MXSession.roomSummary(withRoomId: summary.roomId)` to return `nil` or to return a `MXRoomSummary` instance with `membership` set to `.left`.

#### What happened instead?

After leaving a room `MXSession.roomSummary(withRoomId: summary.roomId)` returns a `MXRoomSummary` instance but `MXSession.room(withRoomId: summary.roomId)` returns `nil`. Note that the `membership` property is still set to `.join` while `membershipTransitionState` is set to`.left`.

Start by tracing MXSession.roomSummary(withRoomId:) and MXSession.room(withRoomId:) for a room after it is left. Compare the returned MXRoomSummary membership with membershipTransitionState and the room lookup result. Done means the summary is nil or reports .left consistently with the expected post-leave behavior.
