 If you have a custom cron schedule defined by a plugin, and a recurring
 event attached to it, you'll get a notice if the plugin is no longer
 available:
 {{{
 PHP Notice: Undefined index: minutely in wp-includes/cron.php on line 111
 }}}

 The notice comes from `wp_reschedule_event()`: [source:tags/3.9.1/src/wp-
 includes/cron.php#L92].

 In line 110, we should replace redundant `0 == $interval` check with
 `isset( $schedules[ $recurrence ] )`.
