When TemplateData defines Suggested wikitext formatting as "block", but no parameters are specified, an unnecessary line break is added.

The wiki syntax end up looking like this:

{{template
}}

It would be nicer if it looked like this:

{{template}}

It repeatedly happens to me with the אישיות template in the Hebrew Wikipedia, which can automatically pull parameter values from Wikidata.

I'm not sure whether the issue is with TemplateData, VisualEditor, or Parsoid, so tagging all.
