Makes faster db consult for users list download 

  * In app/controller/admin/users_controller.rb uses a User.find() method call that uses a :include argument to load the needed Persons with a single sql instead of one sql consult per user.
  * Only call User.find() if the format is csv or xml, to avoid making the
huge sql consult every time the user loads the page.

  * With this change, the downloading time of a users list on csv format
decreased 63%, while on xml format decreased 30%.
  * I've got no guarantee it's enough time to avoid timeout in production
server, though.
  * Not tested on debian.
