Every time the user logs out of matchmaking
or when PlatformManager initializes, fetch a new ticket.
The user might be logging out to the account selection screen
where they might create a new one; a Steam auth ticket is added to
the auth params in the create request and it must be valid.
It *is* possible (though very unlikely) that the user creates a new account
before the first ticket is fetched, since the method that gets a ticket is
an IPromise.
If this way of doing things isn't the best, fix it and I'll merge
