[JIRAALIGN-2332] Filter by Product does not work for Epic backlog when there is Capability in the hierarchy

Issue Summary

Filter by Product does not work for Epic backlog when there is Capability in the hierarchy

Steps to Reproduce

1. Add a Product to a Feature
2. Add a Feature to a Capability
3. Add a Capability to an Epic
4. Go To Portfolio > Backlog > Epic backlog
5. Set the Filter to Portfolio which the Epic is under and the Product added to the Feature in Step 1
