Support for space restricted rooms

[krille-chan]

Description

When a room (version 9) is configured to allow people who are members of space(s) to join, FluffyChat shows "Who is allowed to join this group: null", and I think it also has difficulties parsing join or m.room.member events (while I don't have one of those at hand).

To Reproduce

1. Create a room in Element Web, if necessary /upgraderoom 9 (latest version at the time of writing) or join a room version 9.
2. Open Chat details and look for "Who is allowed to join this group"
3. See "null"

Additional information:
