Clicking '+ Add an access change' results in an error: MissingSchema at /resource/5/access_change/create

We hadn't set the auth_token_url property on the LtiTool object. For production, it's https://canvas.instructure.com/login/oauth2/token (from https://community.canvaslms.com/t5/Canvas-Developers-Group/LTI-1-3-OIDCAuth-url/m-p/216910)
