XWIKI-21608: XWIKI-21509 Broke Upgrade if Tomcat Service is Running, But Not Enabled

If the service is running, we need to restart it in any case, no matter if
it's enabled or not.
However is-active does not always seem to work if the package just gets
installed (see XWIKI-18624), so also check if it's only enabled and try to
restart it then.
