Auth0 key is expired

[nu11pointer]

As described in this issue by the project author, when the Auth0 key is expired, we should expect an exception from the website.

I'm getting that exception right now!

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/flask/app.py", line 2091, in __call__
    return self.wsgi_app(environ, start_response)

  File "/home/admin/saythanks.io/saythanks/core.py", line 342, in callback_handling

Can you please resolve this issue? I would like to test the saythanks platform.

Thanks.
