Static builds fail while dev-server works fine, getCode() is undefined error

Describe the bug I am having an issue with Storybook failing to make a successful static build using build-storybook-command while start-storybook-command is working as expected.

I noticed when change the file @storybook/core/dist/server/common/babel.js in such manner that the createProdPresets-method doesn’t return the babel-preset-minify the build is succesful. For example, like this:

function createProdPresets() {
  return [
    // [
    //   require.resolve('babel-preset-minify'), {
    //     builtIns: false,
    //     mangle: false
    //   }
    // ]
  ];
}

The following errors is given by Storybook when building:

To Reproduce Still working on a reproducible case

Expected behavior I would expect that running build-storybook-command would succeed without errors just like running the start-storybook-command

Additional context I am using a customised version of kcd-scripts which adds TypeScript support for babel and webpack.

@shamin I have made a PR for it 😃 And Happy New Year 😃

Unfortunately the addition of simplify: false in the babel-preset-minify options in v5.3.0-rc.7 doesn’t resolve a similar issue for me.

Removing builtIns: false does allow the static build of my Storybook though.
