Files in lib will be eager loaded and hence will require haml_lint to be
loaded. Since this is only a development dependency, we can't assume
this gem will be available in production, so it should never be loaded
in production.

a warning that both gitlab-secrets.json and gitlab.rb are not included
in the backup.

The `#reset` seems to solve exactly that case.
