Wrappers for TestUtils

[eiswind]

It would be great to have wrappers for the TestUtils from react-dom.

Is something like this on the Roadmap? I could help with this, but I still fail to run any Unit Test at all...

I wonder if Enzyme might be preferable to this. See https://github.com/JetBrains/kotlin-wrappers/issues/325

I made a wrapper for React Test Renderer and might add another for Test Utilities in case I need it in my project.
