wrong dynamic generation file name in bundleRouter.generateSplitFileName

[Kend0r]

Hello

when I make a build on Linux, all dynamic js files are created with the same name, (dynamic/index.js, i dont want the hash)
when I build on Windows, no problem my files came with route name in the prefix (dynamic/src-page-home-index.js)
I figure out the problm was in src/bundle/bundleRouter.ts in generateSplitFileName function
I make a PR for fix it if you are agree with my analysis.

here my configuration :

fuse.runProd({
        uglify: true,
        bundles: {
            app: "app.js",
            vendor: "vendor.js",
            styles: {
                path: "styles/styles.css",
                codeSplitting: {
                    path:"dynamic/$name.css"
                }                            
            },
            codeSplitting: {
                path:"dynamic/$name.js"
            },

        }
})

thank you
