Error in version 0.2.6 #57

@DavertMik
I get a very strange error in the current version
When I make a clean npm-install I get the following line in the lib/codecept.js

global.Helper = codecept_helper = require('./helper');

I have no Idea why. I checked your current master and the line should be:

global.codecept_helper = require('./helper');

Is it possible that some script of yours is causing this problem?

I fixed it locally with the following:

global.Helper = global.codecept_helper = require('./helper');
