Print Report from Manage Case for closed cases doesn't show roles properly

It's not identical to #1948 but might be the same underlying reason.

1. Create a case.
2. Add some roles.
3. Close the Case.
4. Choose Print Report on Manage Case.
5. Look at the roles near the top - they should be there.

Ditto for the Activity Audit which is the same codebase as Print Report.
