Remove unnecessary logging from tests

[JuanCaicedo]

If you run npm test after #136, you'll see a lot of output being logged to the screen that doesn't particularly help.

Any ones in particular. These are the ones I see regularly:

'platform detection:', Object{isNode: false, isInternetExplorer: undefined, isPhantom: true} 'took 28ms to evaluate a complex expression many times, finding 100 matches'

Are they what you are referring too?

It's hard to tell, I wrote that a while ago 😅But my expectation would be that if you run the tests, you only see output related to test successes or failures
