insights bug: dashboards return all insights when no insights are attached

Created by: CristinaBirkel

The issue is basically that if there are no UniqueIDs here, it doesn't add a check at all and everything gets returned.

You can test this out by querying the API for a dashboard that has no insights attached, and seeing that it returns back all of the insights as if they were attached.
