GitLab runner dies when failing to connect via SSL

While installing and registering gitlab-ci-multi-runner on my local macOS dev environment I accidentally typed https for my localhost coordinator URL instead of http. This probably should spit out a friendly "could not connect" message, but it spits out a stack trace instead.

$ gitlab-ci-multi-runner register
