User processes run either as part of user session or as part of user
service. The former is session-xxx.scope, the latter is
user at UID.service. You could add Before=your.service to user at .service
template to make sure your.service is stopped first. Current version of
systemd allows creation of drop-ins in session-.scope.d as well to add
dependency to all session scopes. Check systemd.unit man page.
