Add KD.utils tests

This PR adds tests for `KD.utils` also fixes not logging out `console.log` statements of `PhantomJS` as well.

 These tests not exactly finished but it covers what we need right now. I will focus on `core` + `list` components tests before those.
Ok, thank you for this comment. If you have more of those comments please send them, because I am not anywhere close to a test expert.
