Address logger noise

Fixes #14

Python 2.6 and 3.3 can't get isort. Consider downgrading and pinning isort for those versions?

The assertions to the Popen calls for python > 3 are failing because of

AssertionError: [call(['/sbin/ldconfig', '-p'], env={'LANG': 'C'[252 chars]rue)] != [call([<ANY>, 'which', '*TEST*'], stderr=-1, std[28 chars]rue)]

Not sure who/what is calling that. Assert a specific call to Popen for those versions when running in CI? Be less strict about the index of the call we assert.
