Need a hack for few url expanders

Hello, for some urls the expander does not work. It returns the same url. However using it on browser, redirects to the new url.

```
var urlExpander=require('expand-url');

var url = 'http://cdn.newsapi.com.au/link/375e7272fdc87a7db2d21e25ab9c8320';
urlExpander.expand(url, function(err, longUrl){
    console.log(longUrl);
});
```
