publicPath not being respected when accessing chunks on output module mode

[bsunderhus]

Here's a minimal repro of the problem: https://stackblitz.com/edit/webpack-webpack-js-org-kxd532jl?file=README.md&terminal=build,start

Not sure if this is a bug or intentional,

It seems like publicPath is not being properly respected when loading chunks.

To test this out:

1. npm run build
2. npm start

npm start will run two servers:

1. the main distribution folder with the html file pointing to the main entry output main.js
2. the public folder containing all the chunks generated (port 9010)

If you try to access the application, if everything goes well you should see the number 1 on the page.
This won't happen in this case as webpack will try to access the chunk without properly following publicPatch (publicPath is pointing to http://localhost:9010/)
