YieldWrapper still passed in children when there are no child nodes

[jameshoward]

If there are no child nodes of the component (i.e. it is not being used as a block), there is still a children array passed to the React.createElement containing a YieldWrapper component. We have a component that throws an error (beyond our control) when passed children.

Would it make sense to only create the children/YieldWrapper when childNodes.length > 0 like below? Happy to send a PR.

    let children = props.children;
    if (!children) {
      const childNodes = get(this, 'element.childNodes');
      if (childNodes.length > 0) {
        children = [
          React.createElement(YieldWrapper, {
            key: get(this, 'elementId'),
            nodes: [...childNodes]
          })
        ];
      }
    }

@jameshoward Yes, I think this makes sense. A PR would be great. Thank you.
