Report HTML page broken

In latest tagged stable on npm (`3.0.32`), the report contains a reference to `index-bundle.js` but it is not being generated / copied.


the html file has:

```html

function report (report) { // eslint-disable-line no-unused-vars
window.tests = report;
}



```

Still happens in 3.1 beta. I guess it should never have been pushed to npm as the code seems to match the template here: https://github.com/garris/BackstopJS/blob/UIV2/compare/output/index.html

Yet the bundle is not there.

Can you unpublish these versions under 3.0.x from npm and use tag next or beta
