Title: fixing issue #492 - upload failed, invalid signature

Identified a bug when `cloudinary folder` feature is turned off. The Cloudinary API generates an invalid signature when `folder` is set to `null` in `uploadOptions`. Fixed the issue by excluding `folder` from `uploadOptions` when `item.get('field.paths.folder')` returns `null`.

Sorry ... my bad!
