I noticed that yesterday that Travis failed unusually only Python 3.4 and then 2.7 in a subsequent build in their build environment. However, we don't really need the Python version itself as everything is done within containers.
This also better handles the future where it's unlikely that Python 3.7 will be supported on Travis for Trusty and Python 3.4 won't be supported on Xenial/Bionic, both of which we want to support in gutenberg for the time being.
