[webpack2] bypassOnDebug is required

[jeanbza]

We see errors when we don't provide it. This seems like a bad thing - should it be turned on by default?

    ERROR in ./~/pui-css-backgrounds/images/gray-cloud.png

Fixing it simply requires switching from:

{
        test: /\.(jpe?g|png|gif|svg)$/i,
        loader: 'file-loader!image-webpack-loader'
      }

to

{
        test: /\.(jpe?g|png|gif|svg)$/i,
        loader: 'file-loader!image-webpack-loader&bypassOnDebug'
      }
