Opening the file dialogue in a program, e.g. Firefox or VS Code, opens the nextcloud client.

### Additional info

This happened to me before an an Archlinux install and apparently it's a problem for [other distros and applications as well](https://forum.manjaro.org/t/vs-code-open-file-starts-nextcloud-desktop-client/158149/9).

Closing the client window will put it in background. **Terminating the client process will launch `dbus-:1.2-com.nextcloudgmbh.Nextcloud@4.service` again and again.**

The linked Manjaro issues suggests it's related to nextclouds D-BUS service.

Moving the file from /usr/share/dbus-1/services/com.nextcloudgmbh.Nextcloud.service to elsewhere helps as a workaround but I'm not sure it won't be put back when the client is updated.
