Unit Tests

- Added proper handling for when no command or filter is specified, and
  no rc.default.command exists.
- Improved wording on above error message.
- Fixed typo in previous commit (managed to check in code before the
  build completed, and ultimately failed).
- Now reports errors that occur during initialization at the same level
  of verbosity as during command execution.
