* Fixes#2750: Added missing RF Integration Modules.
Readded the integration modules for both RF integrations.
These are necessary to correctly enable RF support as well as act as
fallback to disable it automatically on missing interfaces.
* Unittests and improved logging for integration modules.
Added a unittest to ensure an integration types instaniates an integration
module without throwing any exception.
Improved the logging should this ever happen at runtime again.
