Travis updates (#50)

* Update to node 6.3.1

* Try adding mongodb as a devDependency

* Try the boron LTS?

* Try sudo:required

It worked in https://github.com/mongodb-js/data-service/pull/68 so hopefully it works here too.

* Revert "Try adding mongodb as a devDependency"

This reverts commit a6606f3b7e2146e88b4dcd22b815a5f0ea15a635.

* Revert "Try the boron LTS?"

This reverts commit ced8acadc0415b6e8c6095ae16c87c390f8fa835.

* Try lts/boron

Let’s see if Travis correctly replaces it to 6.9.x
