Title: Hardening/unit test data to file register context

### Description
- Moved all json/xml data from RegisterContext*_test.cpp to external files
- Found and fixed three bugs during the process:
1. registerContextRequest rendering had no comma for JSON between ContextRegistrations
2. registrationId mandatory for registerContextResponse
3. ContextRegistrationAttribute had an incorrect tag for the metadata
