Writes tests for React to show issue

[vincentaudebert]

This is separating React tests from Preact tests to show an issue with connect.

console.error node_modules/react-dom/cjs/react-dom.development.js:9747
      The above error occurred in the <p> component:
          in p
          in n (created by WrapperComponent)
          in WrapperComponent

      Consider adding an error boundary to your tree to customize error handling behavior.

hiya @vincentaudebert - thanks for doing all this awesome work!

The tests look great. I'm wondering though, if the src changes are necessary given this issue @kaheglar pointed out? It's a silly error on my part that seems like the culprit here.

@developit it's up to you really for the src
I find the original version really "preacty" and I'm more comfortable with the version in this PR with a proper class. But it don't think it matters as long as the tests are passing :)
Feel free to modify it as you want.

PS: I've been checking how things are done with react-redux to rewrite src so I think it's clearly a more "reacty" way than the original one.

Definitely agree that its more react-ey, just not sure if it adds a bunch of weight.

I ended up going with the (fixed) manual inheritance for now.
