 Description   

The main collection scan definition includes an appended UUID, while other foreign collections do not. The reason for this is because during translation of $unionWith, for instance, we only have a Namespace object to lookup the corresponding scan definition. We could either move to (1) just use the namespace or (2) lookup the UUID by namespace in the union/lookup translation.
