Adding end-to-end testing for token replacement in the queue
processing system.

This commit adds a very basic test case for verifying that relationship
tokens are replaced correctly has they make their way through the queue
processing system. This test exports 2 objects with a relationship to
one another and verifies the objects are created with the correct ids.

This class should also test what happens to invalid ids and make sure
things fail gracefully when bad or invalid tokens are detected in the
system.
