Mobile: spaces; /hierarchy always sends children_state

Browse Source 
Mobile:
- The room list's title picks a space: All chats, or one space, which
  narrows the list to its rooms (and its subspaces' rooms).
- A space browser over /hierarchy: the rooms of a space and of its
  subspaces, joined or joinable, with Join; for those who may, adding an
  existing room or a new one to the space.
- New space in the new-chat sheet; invites to spaces show with the other
  invites and open the space when joined.
- Fixes several setState calls that were handed a Future (reloading the
  members, sessions, push distributor, threads), which Flutter rejects.

Server: /hierarchy left out children_state for a room without children.
The spec requires it on every room (an empty list), and SpaceRoom's
omitempty dropped empty lists too, despite its comment. The famedly Dart
SDK fails to parse such a response. The client API now wraps each room so
the field is always written; the federation response, which wants it left
out of the children it lists, is unchanged.
