Inviting a user to an E2EE room does not share keys for history with them, causing UISIs everywhere.

[ara4n]

Steps to reproduce

1. In EX, Invite a user to an E2EE room.
2. The user accepts the invite
3. They never receive the keys for the shared history, so will not be able to catch up on history.
4. EX will show these messages as UISIs rather than surpressing them.

Outcome

What did you expect?

If you invite a user to a room, you should share them the keys they need to decrypt the messages they have permission to. (RHUL might have undermined this, given it lets malicious servers fake invites to steal keys, in which case we might instead need to wait until we have client-controlled group membership).

What happened instead?

UISIs everywhere.

I don't think this is true anymore. The complement-crypto tests at least pass for invited users.
