External status check Retry button breaks when building URL

Summary

When a MR has a failed external status check, clicking the Retry button does nothing. This is because the code fails to correctly build the URL for the API endpoint it needs to hit.

Steps to reproduce

1. Add an external status check to a project
2. Open a MR with a change that will cause the external check to fail
3. Expand the status check widget
4. Click "Retry"
