DDF-82: Retrieve filename with REST endpoint
DDF-82: Only perform resource retrieval when requested

The previous commit performed a resource retrieval even when other
transformers were specified, which is wrong.

We also change log4j to slf4j.
DDF-82: Add tests for resource retrieval

Also refactored the Rest Endpoint tests, and switched it from log4j to
slf4j.
