* Called at startup, to attempt to build a logged-in Matrix session. It tries
* a number of things:
*
* 0. if it looks like we are in the middle of a registration process, it does
* nothing.
*
* 1. if we have a guest access token in the query params, it uses that.
*
* 2. if an access token is stored in local storage (from a previous session),
* it uses that.
*
* 3. it attempts to auto-register as a guest user.
*
* If any of steps 1-3 are successful, it will call {setLoggedIn}, which in
* turn will raise on_logged_in and will_start_client events.
