Bug description

Nextcloud is now always dbus-activated in GTK-environments (see: https://github.com/nextcloud/desktop/pull/6031). That means it starts itself on filesystem access. This is fine by itself. Whats problematic about it is that it also starts up if it's only is installed, not configured on every login and presenting the "login screen". This is a huge problem for multi-user-systems, where only 1 user needs nextcloud. As this currently cant turned off.

Steps to reproduce

Have Nextcloud installed
Login to the PC user account

Expected behavior

On dbus-activation, Nextcloud client should check if its configured and end itself again without showing a window if not.
