Fix T92593: Object preview not re-rendered after "Mark as Asset"

When using "Mark as Asset" the second time on an object (after having
done a "Mark as Asset" and then a "Clear Asset"), the old preview would
be re-used, even if the object was changed meanwhile. This is a bit of a
papercut, so always force previews to be re-rendered on "Mark as Asset".
