GitLab - Confconsole Let's Encrypt module breaking config

[JedMeister]

Ed has reported on our forums that on our GitLab appliance the Confconsole Let's Encrypt module mangles the domain when triggering GitLab to get a Let's Encrypt certificate. It adds an https:// prefix to the existing value of "external_url" in /etc/gitlab/gitlab.rb.

Whilst it may be irrelevant to this issue specifically, it's worth noting that GitLab does not use the "normal" TurnKey Confconsole Let's Encrypt process. It includes it's own mechanism to get a LE cert, so this issue should be unique to GitLab.

[update] After having a quick look, it seems that the issue is likely in this line.
