The render function doesn't pass attrs and slots when rendering dynamic components

Steps to reproduce

• Use the render function (h) to render a custom Vue component (this is not a problem with native HTML elements).
• Pass some props/attrs/slots in the render function.
• You'll see that the component is rendered without the passed props/attrs/slots. As if they weren't passed at all (you'll get the typical Vue warning about required props for example).

What is expected?

The component should render with the passed props/attrs and slots.

What is actually happening?

The component is rendered plain... as if no data was passed.

This works in Vue 3.

Vue 2 render functions work very differently from Vue 3. This was the part that had the biggest changes in Vue 3. Please make sure to read the relevant documentation: https://v2.vuejs.org/v2/guide/render-function.html

I was hoping that the new importable h would behave the same way as the Vue 3's :/
This will add some extra complexity to library authors.

I'll create a small helper to handle this, and maybe propose to add it to vue-demi, or publish it as a standalone library.

Thank you Evan!
