Shallow rendering uses `.type` and throws deprecations

[aaronjensen]

When calling renderer.render() I get:

Warning: Foo.type is deprecated. Use Foo directly to access the class

It seems to be here, and a few other places:

I wonder if #4009 broke this entirely...

.type on a React element still works. It does not work on React classes. It sounds like you're doing .render(Foo) instead of .render(<Foo />).

Spot on @spicyj, thanks for the pointer. The funny thing is it totally worked otherwise... It may be nice if that was an invariant.

Okay.
