Added a failing test that checks if an existing module (or class) exists with a name, that constantize will use the full namespace
Cleaned up the test and simplified down
Refactored the constantize function to use 'false' for searching the ancestors of a module
Fixed the mocking to now expect messages sent with the ancestor flag set to false
