Resolve default onRecoverableError at root init

Minor follow up to initial onRecoverableError PR. When onRecoverableError is not provided to `createRoot`, the renderer falls back to a default implementation. Originally I implemented this with a host config method, but what we can do instead is pass the default implementation the root constructor as if it were a user provided one.
