Fix GROUP BY clause errors

[shemgp]

On default Ubuntu 16.04 install with MySQL 5.7, sip_additional.conf was not being populated. Traced it to mysql having error like:

mysql> SELECT data,id from sip where keyword='account' and flags <> 1 group by data;
ERROR 1055 (42000): Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'asterisk.sip.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
