Federation: Invalid room state when the user joins an empty remote room

[giomfo]

Description

The room state is invalid when an invited member joins a remote room left by the others member.
Note1: the room has been created on another homeserver than the member's one.
Note2: The e2e encryption is disabled in this room.

Steps to reproduce

• Consider 2 users userA and userB, created on 2 different Homeservers.
• userA creates a room, history_visibility is shared (default value)
• userA invites userB
• userA sends some messages
• userA leaves the room
• userB joins by accepting the invite, the room state is invalid NOK
  • the room history is empty
  • the userA is displayed in the room members list

Note3: This issue is not reproduced when userA and userB belong to the same homeserver.. Indeed when the 2 users belong to the same HS, the join request failed (see #1533).

[giomfo]

The data of the remote rooms are not correctly handled on my HS when I'm not present in the room...

This is a similar to #3515

I think this is the same as #6958.
