Bug description

On a remote Ubuntu 22 system there is nextcloud-desktop installed. If I ssh login to that system then the com.nextcloud.desktopclient.nextcloud.service is started on that remote system. Now that service is constantly trying to start nextcloud --background and failing (crashing) because it has no display to connect to.

The error message are somewhat confusing.

jan 26 14:35:54 yangtze systemd[2241]: Started Nextcloud desktop user service.
jan 26 14:35:54 yangtze nextcloud[303069]: qt.qpa.xcb: could not connect to display
jan 26 14:35:54 yangtze nextcloud[303069]: qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
jan 26 14:35:54 yangtze nextcloud[303069]: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
jan 26 14:35:54 yangtze nextcloud[303069]: Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, xcb.

jan 26 14:35:55 yangtze systemd[2241]: com.nextcloud.desktopclient.nextcloud.service: Failed with result 'core-dump'.
jan 26 14:36:00 yangtze systemd[2241]: com.nextcloud.desktopclient.nextcloud.service: Scheduled restart job, restart counter is at 7516.
jan 26 14:36:00 yangtze systemd[2241]: Stopped Nextcloud desktop user service.

This goes on and on, every 3-5 seconds, even after logging out.

Steps to reproduce

1. install nextcloud-desktop on a remote system
2. ssh to that system
3. use journalctl --user -f
   ...

Expected behavior

When ssh logging in to a remote system the nextcloud background service should not be started.
