Allow components using forwardRef

[ddouglasz]

Hello,
Components that use React.ForwardRef seem to be caught somewhere with an error because of a parentPath check. We want to be able to set param type name for such components.

something about this code snippet check seems to be affecting it;

  if (path.parentPath.node.init && path.parentPath.node.init.params.length === 0) {
        return;
   }

I have a PR for this if thats okay.
Please kindly let me know if this has been an issue in the past and if there is a better solution, I will be happy to follow.
