Breaks split-require

[tornqvist]

I just noticed that #43 completely breaks split-require. Only module.exports = whatever work, but all named exports are dropped. I've created a test case in my fork but am struggling to figure out what's wrong.

I'm not fully familiar with the inner workings of split-require and even less so in combination with common-shakeify, @goto-bus-stop, can you see why this change would break split-require?
