Fix #273 Should not use cloneElement and passing new ref within render

Fix #273

This allows passing the ref down to nested components e.g. when using styled components that take an innerRef.

I did not update or add any tests but I think they were still all passing

Im also a huge fan of using styled-components, this would be a gamechanger!
