Bonsai: commit moved bounding objects before IFC-based space generation

The auto-generate-ifc-based-space-boundaries path builds a geometry cache from the IFC file. If a user (or a BDD helper) only moves the Blender object matrix, the cache still sees the old IFC placement and the space footprint is open. Commit any moved visible bounding objects and clear the cache before generating the space.
