Title: Remove wpdb->prepare

wpdb->prepare now shows a warning notice if it is missing the second argument. Details are here:
http://make.wordpress.org/core/2012/12/12/php-warning-missing-argument-2-for-wpdb-prepare/

In this case, no variables are being passed to the query, so I don't think wpdb->prepare is necessary.
