Subject: Fix invite rejection when we have no forward-extremeties (#7980)

Thanks to some slightly overzealous cleanup in the
`delete_old_current_state_events`, it's possible to end up with no
`event_forward_extremities` in a room where we have outstanding local
invites. The user would then get a "no create event in auth events" when trying
to reject the invite.

We can hack around it by using the dangling invite as the prev event.
