Timed autologin not working after logout

[Juha Aatrokoski]

Version 1.2.3-0ubuntu1 of lightdm (in Precise) fixed timed autologin for the initial startup (see bug #902852), but timed autologin still does not work after logging out from a session.

It is logical that *immediate* autologin doesn't work after logout, but the purpose of *timed* autologin is to allow other users a chance to log in, and to log in a default user if no one does. As such, timed autologin should work every time the login screen is presented (and there are no users logged in via lightdm), i.e. also after logging out from a session, not just the first time lightdm is started. (This is also how it worked with gdm in Lucid.)
