SolidModel, postrender_ops() issue

[yfangad]

The following postrender_ops shows Error : Difference failed - BOPAlgo_AlertTooFewArguments error.

(
                "l1_gnd",
                SolidModels.union_geom!,
                ("l1_gnd", "bump_surface",2,2),
            ),
            (
                "l2_gnd",
                SolidModels.difference_geom!,
                ("l2_gnd", "l1_gnd",2,2),
                :remove_object => true,
                :remove_tool => false
            )

However, after changing the group name of union_geom! from "l1_gnd" to something else, the error goes away.

(
                "foo",
                SolidModels.union_geom!,
                ("l1_gnd", "bump_surface",2,2),
            ),
            (
                "l2_gnd",
                SolidModels.difference_geom!,
                ("l2_gnd", "foo",2,2),
                :remove_object => true,
                :remove_tool => false
            )

I wasn't able to reproduce this, so can you check if #156 (] add DeviceLayout#gp/fix-155) solves this? Should be equivalent to adding :remove_object=>true to the first operation, but that PR automatically sets those keyword arguments when the object/tool is also name of the destination group.
