[Phaedrus Leeds <mwleeds src gnome org>]

commit a4190caa85842de9af9880729c41b07945265cf2

    panels: lock: Disable lock screen when autologin is enabled
    
    Note 2020-08-26: This patch has been in Endless OS since 2014; proposing
      it upstream. Presumably if you have autologin enabled you're not
      depending on your account password to keep your computer secure.
