Return empty unicode in ContentExtractor.top_meta_image() when no image is found. It was returning the article's url.
Example:
http://www.usnews.com/news/entertainment/articles/2015/01/15/boyhood-keaton-moore-are-oscar-favorites-in-vegas
(note that USNews often updates its articles, e.g. by adding an image -- at the time of writing it was without images)
