会话记录为空的时候会显示NULL转int64错误

staff.go单元，这段代码增加IFNULL处理

    err = DB.Model(&GroupChat{}).Where("ext_corp_id = ?", extCorpID).
	Pluck("IFNULL(sum(today_join_member_num),0) as today_groups_increase", &cs.TodayGroupsIncrease).Error
if err != nil {
	err = errors.WithStack(err)
	return
}

err = DB.Model(&GroupChat{}).Where("ext_corp_id = ?", extCorpID).
	Pluck("IFNULL(sum(today_quit_member_num),0) as today_groups_decrease", &cs.TodayGroupsDecrease).Error
if err != nil {
	err = errors.WithStack(err)
	return
}
