Remove unnecessary `minimize` option for css-loader

Line 20 in 86d4970

minimize: process.env.NODE_ENV === 'production',

We shouldn't need this, since we use OptimizeCSSPlugin in the productionbuild anyway, right?

Why delete css-loader minimize: process.env.NODE_ENV === 'production'.
I know OptimizeCSSPlugin can compress；
but webpack.prod.conf.js new ExtractTextPlugin({ filename: utils.assetsPath('css/[name].[contenthash].css?v=111111')}),
Css packaged without compression did not go heavy
