VueNodeViewRenderer should return `null` for `contentDOM` for a non-leaf node with no `NodeViewContent`

[segevfiner]

Please describe your changes

For a non-leaf node with no NodeViewContent return null instead of this.dom, this allows the node view itself to handle rendering the child content, instead of overriding the entire node with its child contents, not allowing to render it at all.

How did you accomplish your changes

I changed a line of code.

How have you tested your changes

In my own project.

How can we verify your changes

Create a node view that has child content, but no NodeViewContent.

This is also necessary in my use case. I found out about this PR by stopping at the same line in the code that was modified by the OP. If this PR were merged, how could a node view modify its own content? Do you know if there's a Tiptap or ProseMirror API for this?
