Fix the generic placeholder for attendees

People with just regular attendee badges were tripping the volunteer_placeholder email check because it didn't check a.staffing. They then (correctly) didn't actually get sent the volunteer email because they were not volunteering. Now the volunteer_placeholder function includes a.staffing so people can actually qualify for the generic placeholder.

Also fixes an issue where deferred attendees would also qualify for the generic placeholder because I was checking the truthiness of the function itself instead of calling it.
