Fixing issues with babel core on a fresh install and addressing batch test failures

[jdollar]

Running into this issue when running a new 'npm intall':

The package.json babel-core upgrade came from these: Original issue with the fix: https://github.com/webpack/webpack/issues/2463 Linked issue in babel-core: https://github.com/babel/babel/issues/4306

In addition to the install failing there were also two tests failing for the batch dispatch tests. Had a "TODO" comment stating nothing was getting dispatched and the error I was getting was:

Updated the batch test file to just dispatch a null in addition to getting dispatched from the timeout.
