metro-bundler: fix jest-haste-map require 

Summary:
Addresses https://github.com/facebook/metro-bundler/issues/62

Apparently with some versions of `jest-haste-map`, the nested source file returns the module wrapped with `default` instead of the exports themselves (due to some ES6 babel transform, I am guessing). I wasn't able to reproduce this myself yet, but I think a good first step is to avoid using nested library files in the first place, ie. only use what's exported at the top-level.
