Ensure GitLab CI project exists when CI service is activated manually

When I check activeated checkbox in project services for GitLab CI it cause half-working state when gitlab_ci_project is missing. This patch fixes it until we have proper behaviour implemented later

This fix also bring us to the point when fork of project is a bit broken and have unnecessary code so I made cleanup.
