When trying to analyze a stats.json for a webpack bundle generated off
of an array webpack.config.json webpack-bundle-analyzer was throwing:

Could't analyze webpack bundle:
TypeError: Cannot read property 'assets' of undefined

This bug was probably introduced in
#376

Example webpack config to generate a stats.json file that causes the
crash:

function getConfig({ config }) {
  return {
    mode: 'production',
    entry: './src/index.js',
    performance: {
      hints: 'warning',
    },
    optimization: {
      minimize: true,
    },
    output: {
      filename: `${config}-[name].js`,
      chunkFilename: `${config}-chunk-[name].js`,
      path: `${__dirname}/`,
    },
  };
}

module.exports = [{ config: 'config-1' }, { config: 'config-2' }].map(getConfig);

This looks good to me, thank you!

I'll merge once Travis CI happens to work again.
