Load item from truncated reference

This use case intends to load an entity by its reference received by peer. It is internally using the specific use cases of each entity:

• If the reference references a Token, fetches the Token just like Load Token created by others.
• If the reference references a RelationshipTemplate, fetches the RelationshipTemplate just like Load RelationshipTemplate created by others.
• If the reference references a File, fetches the File just like Get or load File.
• If the reference references a DeviceOnboardingInformation, fetches the DeviceOnboardingInformation just like Get Device Onboarding Token.
