How to clear a Project's Failed Deletion Warning?

I tried to deleted a project in our EE Gitlab 11.9.12-ee. It didn’t work because it couldn’t remove the registry images. I know how to fix that issue, however we decided after that fact to keep the project. But now we see “This project was scheduled for deletion, but failed with the following message: Failed to remove some tags in project container registry. Please try again or contact administrator.” This is a banner on that project and we cannot remove it. We tried setting in the gitlab rails console “p.pending_delete = false” and the cache clearing commands like “gitlab-rake cache:clear”. At this point I just want that banner to disappear.
