Fixed error on canceling editing railing/roof

Since we do not update representation for railing / roofs and just mark them wtih `tool.Ifc.edit(obj)` their previous representation may still be incorrect. So we restore the previous representation just using bmesh update method.

For example if create a new roof, enter editing roof properties mode and then cancel editing, then it would result in "Failed to process a shape" because roof still had just empty Body/PointCloud representation.
