Title: A block helper can return a string. It needn't be logged as a problem.

My previous pull request to not surround HTML with paragraphs was not accepted. It contained this other fix which I think is still worth having on its own: JsonML supports strings of text, not just tags.

This patch changes the warning message to not complain when the text is a string either.
