SuggestionBuilder doesn't need to extend ToXContentToBytes
This changes the class from extending the abstract class to implementing the ToXContent interface only. The former could lead to unexpected behaviour when trying to display the object, since the "toString()" method inherited from ToXContentToBytes would create an error message because the SuggestionBuilders toXContent() methods don't render complete json objects.
