recurrences not listed

Cause: 
Not list recurrences after add.

MySQL_ERRO:
#1055 - 'DATA_BASE_NAME.cron.domain_id' isn't in GROUP BY 

Solution:
add this fields in the GROUP BY (cron.id, domain_id, invoice_id, start_date, end_date, recurrence, recurrence_type, email_biller, email_customer, index_name)
