Wrong hadnling of 302 redirects

[oaleynik]

Hi everybody,

To describe this issue let's start from official Read API docs: https://build.phonegap.com/docs/read_api

For example the GET https://build.phonegap.com/api/v1/apps/:id/icon method contains the description of two different behaviors:

"In the successful case, this API method will return a 302 redirect to the icon file - the actual body of the response will point to the resource in question"

That means, that if we will follow the 302 redirect, than we will recieve the actual icon data, in other case - we should get the object with the location field, which points to the requested resource.

{
    "location":"http://s3.amazonaws.com/build.phonegap.com/some-long-guid/icon.png"
}

Currently, if we pass the followRedirect: false to API call, than we get the response in err parameter of callback, wrapped into Error object. So, considering the next example:

api.get(path, {followRedirect: false}, function(err, data) {
     return cb(err, data);
});

... we will get the undefined data param, and [Error: "{location: "..."}"] in error param.
