[miaulalala]

We're not doing attendance properly. The RFC specifies the following flow:

1. The Replying Attendee (RA) writes into their own scheduling inbox (negotiating any significant changes via If-Schedule-Tag-Match header).
2. The server sees changes to the attendance of RA and processes the changes for the organiser and all OTHER attendees.
3. The RA client retrieves back the RA event to get the scheduling information for the organiser.

We're missing step 1, which is why the attendance isn't updated for the RA.
When accepting an invitation via token URL from Email, only step 2 happens. Step 3 would have to happen when opening the calendar, which already does AFAIK.
