Tests Failing

With the changes made to the default constructor some of the tests fail. (Located [here](https://github.com/Konloch/SafeYAML/tree/tests))

These will need to be rewritten to support the original default constructor for each specific test that needs it.

Start by inspecting the tests in the linked tests branch and identify which failures depend on the changed default constructor. Update the affected tests to use the original default constructor behavior, then confirm the test suite passes.
