add assignRoleToSecurityGroupOnParent method to call assignRoleToSecurityGroup...

add assignRoleToSecurityGroupOnParent method to call assignRoleToSecurityGroup on the parent object, from unrestricted code.
The permission is necessary on the role definition object, not the parent object.
As a bonus, this will no longuer fail if the acquisition parent is not the real parent.
