On Windows with Node 0.11.13 grunt.config returns an empty object #1166

1. Install Node 0.11.13 on Windows 8.1
2. Checkout https://github.com/mzgol/grunt-check-dependencies
3. Run npm test

Effect: https://ci.appveyor.com/project/mzgol/grunt-check-dependencies/build/3/job/v5ik5b0f0b7nui91

This is because in this line:
https://github.com/mzgol/grunt-check-dependencies/blob/b904397b9ffc459e8a175d0026bd4063eb1f6676/test/spec.js#L37
grunt.config(['checkDependencies', 'ok', 'options']) returns undefined. grunt.config() returns an empty object.

It works fine on OS X in both Node 0.10.29 and 0.11.13 and on Windows 8.1 on Node 0.10.29.
