[TESTING] Fixup Part 1 (- WIP PR #175 -)

Changes in file multicast/exceptions.py:
 - minor changes

Changes in file tests/__init__.py:
 - expanded doctest finder

Changes in file tests/test_exceptions.py:
 - aligned class name with [CEP-9](https://gist.github.com/reactive-firewall/d840ee9990e65f302ce2a8d78ebe73f6)
 - added more test cases to improve coverage slightly.
