Right now we get an ugly error if someone uploads a notebook with the same name as an existing notebook due to the uniqueness constraint of the notebook name. We should prompt the user to confirm that they want to overwrite the existing notebook and then allow the upload if they are the author of the original. Otherwise return a more useful error message.
