Fixes specs on create_test_failure_issues

The CI project path is being leaked causing FOSS and Security failures because the project path is different from the canonical one. Examples:

• FOSS: https://gitlab.com/gitlab-org/gitlab-foss/-/jobs/4010133198
• Security: https://gitlab.com/gitlab-org/security/gitlab/-/jobs/4010496201

Also ensures the description of the issue is actually stubbed.
