Lint JS files w/out extension too (#453)

Prior to this change, JS files without extension had not been linted.

To match them, we need a combination of positive and negative globbing
that does not mix well with the existing file selection for linting. Thus, we use
npm-run-all to run two ESLint invocations unconditionally in sequence
while still preserving the error code.

* Lint JS w/out extension too
* Fix newly surfaced linting errors
* Make use of npm-run-all for test script too
