fix(proxy): proxy restart does not work on domain

- When you restart the proxy on an instance domain, the proxy stops and is removed, but never restarted. So you loose access over the domain and have to go in over IP and Port.
This is because we are doing the restart directly in the UI instead of in the background via a job, and the proxy is serving the UI domain.
