TypeError: Cannot read property 'filter' of undefined

[sq3]

After installing the tool via npm, I've got the following problem. It comes every time I use wunderline with any option for example "inbox"

 $ wunderline inbox
/usr/local/lib/node_modules/wunderline/util/get-inbox.js:27
    var lists = body.filter(function (item) {
                     ^
TypeError: undefined is not a function

I'm going to be adding proper authentication errors soon (see https://github.com/we-are-next/wunderline/issues/41)
