Fix: Publishing cxId to DTR

[eschrewe]

Description

• i noticed that when the triggerPartTypeRetrievalTask method is called, there is currently no mechanism to make sure that a cx id that was fetched as a result of that method call is immediately published to the respective shell descriptor at the DTR.
• the fix for this is to initiate a DtrRegistration Task instead of just a PartTypeInformationRetrievalTask. A DtrRegistrationTask will always trigger a PartTypeInformationRetrievalTask when it notices that there is a missing CX id from a supplier partner. But beyond that it will also send an update for the approriate shell descriptor to the DTR
