/**
 * Event Tickets - Remove Checked-In Attendees from wp-admin table
 *
 * Can help the Attendees List table screen's performance after some of the attendees have been checked in.
 * Modified from Barry's original version on May 24, 2017, to support all ticket types.
 * Ideas: only do this if a specific query parameter exists, or only do this if a button is clicked (but then the point about this being a performance improvement would no longer be valid)
 *
 * @param $query
