Auto-deploy webhook toggle should be turned on for the initial trigger if deployed from github repo

Motivation

If the "auto-deploy" webhook is toggled off before initial webhook trigger, image gets stuck on hello-porter (as one would expect). This is unintuitive from user's perspective - the first webhook trigger should result in a redeploy regardless of whether the toggle is on or off.

Requirements

Web service, worker, and job all need to either disable the webhook toggle by default on initial deploy, or enable the webhook regardless of the toggle value if image is set to hello-porter.
