Assert when adding geometry cache asset as a component to a blueprint actor

When adding an asset directly to a blueprint, it is not in the streaming components, so the assertion fails when setting the geometry cache.

• In QA Game, create a new actor blueprint and open it up to edit it
• Find this asset: GeometryCache'/Game/Sequencer/FrameAccuracy/AlembicContent/GeometryCache/BoxAlembicCache.BoxAlembicCache'
• Drag it from the content browser into the Components hierarchy of the new blueprint and observe the following assert in FGeometryCacheStreamingManager::PrefetchDataInternal

RESULT

Assertion failed: IsManagedComponent(CacheComponent)
