Orphaned uploads of type vulnerability remediation on staging-ref

There are currently 83 uploads queued for sync on staging-ref's secondary Geo site.

All of the objects have model_type Vulnerabilities::Remediation. None of the corresponding model objects exist anymore.

In gdk, creating an instance of Vulnerabilities::Remediation correctly creates the corresponding upload object, registry entry, and syncs to the secondary. Calling destroy! on the instance removes the object, and the registry entry.

Manually running qa/specs/features/ee/browser_ui/10_govern/vulnerability_management_spec.rb against the GDK instance also does not leave the orphaned registry entry.
