How to Review

The original issue (#6594) happens if you leave the classifier open long enough for your bearer token to expire, so you might need to open the classifier in a tab and leave it for a couple of hours. With the changes here, an expired token should always be refreshed, as long as you don't allow your Panoptes refresh token to expire. I think refresh tokens are good for up to 2 weeks.
