Title: accounts-daemon service, fix gnome-shell

For some reason, gnome-shell worked out without gnome-settings-daemon gschemas on my system. After a garbage collect + rebuild, it didn't work anymore. Turned out it was missing gschemas dependency.
The accounts-daemon is used for knowing some user information in gnome-shell, however we should forbid changing accounts from the gui.
