## Summary
To determine which services were installed, cloudflared, was using the command
`systemctl status` this command gives an error if the service is installed
but isn't running, which makes the `uninstall services` command report wrongly
the services not installed. Therefore, this commit adapts it to use the
`systemctl list-units` command combined with a grep to find which services are
installed and need to be removed.
