and remove the old conference call stuff while we're at it: enough
time should have passed since those mistakes that we can move on.
The old conference call rooms will still appear for anyone whose
account dates back to that time, but they've presumably been appearing
in any other matrix client they used too.
We were expecting this function to return a string user ID, but it
returned a user object
Make it return a user ID and add jsdoc to say what it returns.

In the DM guessing code, prefer the oldest joined member if there's
anyone in the rom other than us. Otherwise, fall back to the old
behaviour.

- Set the verb for the people section to "tag as direct chat". This requires some CSS modifications to Riot because it's a long bit of text relative to, say, "demote".
- Because it's quite useful to be able to set the DM status of a room with just a boolean, add a convenience function for guessing a DM member and setting the DM flag on that room with the resulting member.
and mark it as one if so.
Also change the heuristic to only count rooms with 2 total members rather than 2 joined members, otherwise this is going to mark any room as a DM if someone creates a room, invites a bunch of people and you happen to be first to join.
