There are two issues:

1. When a Wiki was disabled, the spec was still trying to create a
Wiki page, which would cause Gitaly to create the repository and fire
hooks. Since Rails isn't running an internal API server, this fails.

2. For private Wikis, the Wiki repository needs to be created with the
:wiki_repo trait in order to clear hooks to prevent Gitaly from
contacting the internal API server.

Running git log --full-history -- features/steps/project/builds.rb, you can
see that this was renamed to features/steps/project/builds/artifacts.rb in
2016 via bf7aac74. You can't see the actual changes in GitLab, but
they show up if you run git diff da866795..30e4d3ce.
