switch_representation not to break with temporary mesh representations

I've found a bug that if you have some object that consists of extrusion and can be edited in profile edit mode, when you finish editing, it would remove the type object (and I guess the other occurences objects).

It happened because during edit mode it's using temporary mesh data and `switch_representation` would replace this temp mesh data with new representation and remove the old mesh data that might still used by the other occurences and the type.

The issue also was leading to a crash during `box.template_icon(icon_value=AuthoringData.data["type_thumbnail"], scale=5)` if you had BIM Tool thumbnail preview opened in the process - removing type object would make thumbnail icon become invalid leading to the crash.
