When using System.import with webpack 2 and web-dev-server

[aight8]

It happen when use webpack-dev-server with System.import in a bundle file and change a file. Then this error happens:

xxx/node_modules/extract-text-webpack-plugin/index.js:22
            if(c.initial) return;
                ^

TypeError: Cannot read property 'initial' of undefined
    at ExtractTextPlugin.<anonymous> (xxx/node_modules/extract-text-webpack-plugin/index.js:22:8)

Output chunk.chunks:

  name: 'text',
  modules: [],

+1 on this...

This could use a little standalone example against import().

Based on the error I would say this is actually the same as #406. The code has changed to .isInitial().

Closing this as a result.
