Generate a diff, no caching.
This implementation uses generateTextDiffBody() to generate a diff based on the default serialization of the given Content objects. This will fail if $old or $new are not instances of TextContent.
Subclasses may override this to provide a different rendering for the diff, perhaps taking advantage of the content's native form. This is required for all content models that are not text based.
