Issue
Resetting dconf setting during reboot. In my opinion slick-greeter shouldn't reset user defined settings. I would like to able to use ansible to configure slick-greeter with community.general.dconf, but currently when rebooting device slick-greeter will reset settings. Restarting lightdm will not reset dconf settings as expected.

Steps to reproduce

1. Use dconf to configure /x/dm/slick-greeter/clock-format to '%d.%m.%Y - %H:%M:%S' as lightdm user. Use command sudo -u lightdm dbus-launch dconf write /x/dm/slick-greeter/clock-format "'%d.%m.%Y - %H:%M:%S'"
2. Restart lightdm service
3. Login and reboot

Expected behaviour
dconf settings are respected and not resetted.
