This PR reverts #820 which broke deployments on Envoyer.

I was pulling the last of my hair out for hours trying to figure out why horizon:terminate was not killing Horizon on new code deploys to Forge via Envoyer.

Manually SSH'ing in to the queue server and running the horizon:terminate command sometimes worked, (shown at the top of the screenshot) and sometimes just returned no response at all, and the same horizon supervisors were still running, (shown near the bottom of the screenshot).

I was able to restart Horizon by restarting the daemon manually through the Forge UI, but this wasn't a good solution.

After updating Horizon from 4.3.0 to 4.3.1, the issue has been fixed for me, thanks!

Here's a screenshot of what was happening before the fix. 😅
