Andrej730 a2ff63f9ec Fix issue editing object placement that shares it's axis placement with other placements 
If multiple object placements were reusing the same IfcAxis2Placement then editing one of them would remove IfcAxis2Placement ignoring it's inverse references making all other object placements invalid.
