Use the last_used value from the auth cache database to check for cache lifetime when authorizing

[marcemmers]

Describe your changes

When trying to authorize a token that has passed its lifetime in the cache but is not cleaned up yet by the 15 minuted automatic clean up, it would still get accepted. This prevents that and removes it from the cache during the authorization.
