entry.url is using Windows separator

Hi, there.

We are trying to precache our static assets for Bootstrap in this PR: twbs/bootstrap#23533

With workbox-build v2.0.0 on Windows, I'm getting this:

  {
    "url": "about\\index.html",
    "revision": "f9307e727e85be5a2a420ca9a44a4f01"
  },

I can just do a replace for the backslashes, but I wonder if this should happen in the first place? I know that URLs do not use backslashes but here maybe this is normal?

Thanks!

No this is definitely a bug, so thank you for raising this. I'm not sure how this is happening though as we have tests to check for this. Will have a look.

I had a quick look and it seems the issue is caused by path.join here

If you use path.posix.join it works but I guess that is not the place to make the change.

OK I think I figured it out; see #774.
