Tranformer - CSP specific Authenticate is not used

Hi,

While adding AWS support for GCZ, I noticed that our own class implementing IAuthenticate was properly used when calling some API Endpoint, but not during the application launch, when calling one of the FeatureCacheSynchronizer. The traceback is:
