Failed to compile message without any detail.

Created by: RIP21

This is issue created for discussing fix of the weird common Alphas 2.0.0 error that looks like that:

I did some research trying to find the root cause and it seems that I found it.

Seems to be an issue in formatWebpackMessages.js

// Remove unnecessary stack added by `thread-loader`
  var threadLoaderIndex = -1;
  lines.forEach(function(line, index) {
    if (threadLoaderIndex !== -1) {
      return;
    }
    if (/thread.loader/i.test(line)) {
      threadLoaderIndex = index;
    }
  });

  if (threadLoaderIndex !== -1) {
    lines = lines.slice(0, threadLoaderIndex);
  }

This piece is deletes everything after 'thread-loader'. So when you have an error or warning it will be striped out to the path only. So message like that:

./src/elements/FormSignIn/index.js
Module Warning (from ./node_modules/thread-loader/dist/cjs.js): <<<< Takes this line index

 @ ./src/App.js
 @ ./src/index.js
 @ multi ./node_modules/revolut-react-scripts/config/polyfills.js ./src/index.js <<< removes all till that line

End up like:

./src/elements/FormSignIn/index.js

So effectively changing

  if (threadLoaderIndex !== -1) {
    lines = lines.slice(0, threadLoaderIndex);
  }

to

  if (threadLoaderIndex !== -1) {
    lines.splice(threadLoaderIndex, 1);
  }

May fix this, I'm not sure about other errors and warnings formats so a little discussion will be a nice thing to do before I open a PR if you like.
