stub or Stub in test-gently.js#l248 / testExportsName?

I've linted the code for this project and submitted a pull request, but it's detected an issue I'm not sure about and I haven't resolved.

JSLint flags `stub` as declared (as `new Stub`) but unused at [test-gently.js#L248](https://github.com/PlNG/node-gently/blob/master/test/simple/test-gently.js#L248) or variable `stub` in `testExportsName`, but `Stub` itself is used later.

Is that intended?
