`tests` folder should be within the package, not a sibling.
Spec files should not automatically have a `_`.

This should be saved for widgets/class that are intended to be mixed in and therefore their module id's start with a `_`.

For example: [`ijit` Specs](https://github.com/agrc/agrc.ijit/tree/master/widgets/tests/spec)
Cleaned up unused variables that cause linting to fail.
