Plugin fails on dynamic imports

[DreierF]

Using dynamic imports like

import(/* webpackChunkName: "login" */ './login/LoginPage')

causes the plugin to break. It throws with:

ERROR in ./src/Index.ts
Module parse failed: Unknown node type Import.
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
Error: Unknown node type Import.
