Inconsistent asset property change propagation

Changes in an assets collision profile are picked up only when an instance is created, while changes to the assets collision shapes are propagated to instances. This represents an inconsistent handling of property changes.

• Open a project.
• Place a static mesh using default collision.
• Change the collision profile of the static mesh asset.
• Place a new instance of the static mesh using default collision.

Result: The first instance uses what was set as the profile, while the second uses the new profile, because the default is picked up on creation and not propagated to instances on change.

• Repeat these steps, but instead of changing the collision profile, add a collision shape.

Result: Both instances will reflect the added collision shape, because these changes are propagated back to instances.

Expected: That asset property changes are consistently always picked up at creation time, or always propagated.
