Title: added call to action in link page post

The call to action is used in mobile app ads (https://developers.facebook.com/docs/reference/ads-api/mobile-app-ads/#create). In this case the link parameter is not required so I made it optional.

Also I fixed an issue with the exception, because the error in json.load is not always ValueError.
