TypeError: undefined is not a function in obj.hasOwnProperty(k)

[aaronjensen]

querystring objects seem to break rollbar. It may have something to do with nodejs/node#6289

This is the property that is being scrubbed that is causing the failure:

  GET: { color: '999' },

Exception:

/Users/aaronjensen/Source/my-app/functions/node_modules/rollbar/src/utility.js:129
      if (obj.hasOwnProperty(k)) {
              ^

Thanks @aaronjensen - we're looking into this today.

Object.create(null) ugh; I have a solution, will fix

Thanks for the quick turnaround! Would you mind dropping a note here on the next release so I can upgrade and remove my workaround? Thanks
