added test for object for steamroller bonfire

[Greenheart]

Now tests if code works with objects.

Incorrect code like the following will not work since it can't handle objects.

function steamroller(arr) {
  arr = arr.toString().split(',');

  for (var i = 0; i < arr.length; i++) {

    test = parseInt(arr[i], 10);

    if ( !isNaN(test) ) {  // if test not is not a num
      arr[i] = test;

    } else if (arr[i] === '') { // Object is '' after .toString(), so remove empty strings

      arr.splice(i, 1);
      i--;
    }
  }

  return arr;
}

Has this been tested locally and linted?

I've tested it. I have not linted it, but should not need linting, it's only a single line of JSON.
Which linter is used for JSON, by the way? I've only heard ESLint for the JavaScript.

@ahstro i use this http://jsonlint.com/ It requires copy-pasting but it's very good. It most likely doesn't need linting as it's just a one line change but it's a good practice when contributing :p

@benmcmahon100 I'll use that one in the future!
