   _filterAssociationInstances is used to filter the set of possible return

   the associators and associatorNames operations.  It returns the ObjectPaths
   of the set of objects that pass the filter tests.

    @param assocInstance     - The target association class instance
    @param sourceObjectPath  - The source ObjectPath
    @param resultClass       - The result class. If there is no resultClass,
                               this is String::EMPTY.
    @param resultRole        - The result role. If there is no role, this is
                               String::EMPTY

    @return   the ObjectPaths of the set of association instances that pass
