Warning about notFoundError is shown when rendering root route and there's no defaultNotFoundComponent set, even though it renders successfully.

I had that error my first time using start, and I solved it by adding the notFound component, but nevertheless it has been marked as a bug since it does seem to be one. I would like to work on that as my first contribution.

@soyricardodev adding the notFoundComponent just silences this warning. however, there shouldn't even a not found error be thrown here.
