How Has This Been Tested?

Removed node_modules folder and ran npm install

https://unpkg.com/promise-polyfill@7.0.0/dist/promise.min.js
 > vendor/promise.min.0f2d5308.js ... done!

The workaround I proposed used the minified version for simplicity's sake.

We should still respect the $suffix variable, i.e.

'https://unpkg.com/promise-polyfill@7.0.0/dist/promise' . $suffix . '.js'
