Bad test

- Test was ensuring that if a factory exists for a class, then the
  abstract factory will not be queried.
- Unfortunately, the way the test was written, an engine-level fatal
  error was raised due to a missing constructor argument, which in turn
  does not raise the ServiceNotCreatedException.
- Altered the constructor to raise an exception if the expected type is
  not provided.
