Fails with newer versions of cz

[cvockrodt]

When installing with the latest version (1.8.2) of cz, node fails to run with the following error:

config.defaults({
       ^

TypeError: config.defaults is not a function
    at Object.<anonymous> (/opt/putio_client/app.js:11:8)
    at Module._compile (module.js:652:30)

    at startup (bootstrap_node.js:188:16)
    at bootstrap_node.js:609:3

Hard-coding the version to 1.3.1 allows it to run correctly. I'm not sure which version is breaking

It looks like it fails at cz=^1.6.0
