Fixed #245 -- The first ``AccordionGroup`` can now be set ``active=False``.

- If the user initializes the first ``AccordionGroup`` with the
  ``active=False`` kwarg, it will no longer be initially visible at
  page load.
- The original default behavior, which renders the first group when
  the ``active`` kwarg is not set at all, is still retained (and therefore,
  the change should be fully backwards compatible).
- Unit test written for new functionality.
- All previous unit tests pass.
