Travis: Always just test on newest Node.js version

I think I've made too many commits along the lines of "tell Travis to also test on the yet again newly released Node version", when I could just have done this. Wah. I don't really care very much about old version compatibility because anyone crazy enough to try something like this is crazy enough they are or should be running the newest Node.js anyway.
