Misleading message when pipeline is complete

Summary

After a pipeline finishes running, the Security Reports MR Widget show as there is no new vulnerabilities. However, on page refresh, this message is gone and the correct one appears.

Steps to reproduce

This is a bit random, so I'm not exactly sure about the steps but what worked for me was:

1. Create an MR that introduces a new vulnerability
2. Wait for the pipeline to complete
3. After the completion, you should see the security reports MR widget with no new vulnerabilities detected message
4. If you don't see it, submit another commit and it should trigger a new pipeline
5. After the completion, now it should appear (hopefully)
6. Refresh the page and you should see a different message
