Handle tokens created and quickly revoked with insufficient timestamp precision
In the event that the revocation event is created at the exact same timestamp as the token's creation timestamp, the event's issued_before will equal the token's issued_at and will thus not be revoked (according to the current code). This is much more likely to occur when a token's issue_at timestamp is rounded to whole seconds (rather than carrying microsecond level precision), as they are with Fernet and MySQL.
