Simpleads being reactivated incorrectly

There is a bug in _simpleads_activate_deactive_ad() that results in Simpleads being reactivated (re-published) incorrectly at every-other cron run if start date is not set, and end date is in the past.

This block:

  elseif ($start_time == '' && $end_time != '') {
    if ($end_time <= $now && $current_status == 1) {
      $node->status = 0;
      if ($who == 'cron') {
        node_save($node);
      }
    }
    else {
      $node->status = 1;
      if ($who == 'cron') {
        node_save($node);
      }
    }
  }

Should be changed to:

  elseif ($start_time == '' && $end_time != '') {
    if ($end_time <= $now && $current_status == 1) {
      $node->status = 0;
      if ($who == 'cron') {
        node_save($node);
      }
    }
    elseif ($endtime > $now && $current_status == 0) {
      $node->status = 1;
      if ($who == 'cron') {
        node_save($node);
      }
    }
  }

else { is changed to elseif ($endtime > $now && $current_status == 0) {
