More consistency for invite records table

- Autojoined child spaces are recorded as invited
- Update entry when reinvited
- Delete entry when uninvited or removed from room
- Allow linking with spaces you moderate, even if you didn't invite
- Store power levels immediately for new invited rooms
  - Mark members as missing profile in this case
- Only delete from invite table if it left the space
