Support forwarded ref component

[mathieudutour]

Trying to suspend in a react component created with React.forwardRef would throw the following error:

A React component suspended while rendering, but no fallback UI was specified. Add a <Suspense fallback=...> component higher in the tree to provide a loading indicator or placeholder to display.

With this patch, shimElement supports forwardedRef component and the error disappears.

Thanks very much for this. I'll look at it as soon as I get a minute.

In meantime, could you please:

1. Add a test
2. Fix lint errors (CI seems to be disabled right now due to changes at Travis, but I can see from the code style that lint would fail - run npm run lint to check linting)

Do you think same problem would occur with other wrapped components e.g. React.memo() etc?

Also, what version of React are you using?

Add a test

I wasn't sure where to add it as I didn't find any related to that part of the code. Could you point me to it?
