FK Constraint Error deleting Users on SSO Site to Principals

FK Constraint Error deleting Users on SSO Site to Principals
The unit test, TestSSOComponent.java, fails with a

java.sql.SQLException: Integrity constraint violation: SSO_SITE_TO_PRINCIPALS_FK_2 table: SSO_SITE_TO_PRINCIPALS in statement [DELETE FROM SECURITY_PRINCIPAL WHERE principal_id = 422 ]

error. It seems that Torque is not correctly generated the cascading deletes for HSQL.

This error does not exist on other databases tested.

Disabling the unit test until this fixed.
WARNING: deleting users with SSO credentials will cause a FK error and the user won't delete (again this is only a bug with HSQL)
