Fixed issues related to MySQL ONLY_FULL_GROUP_BY

Browse Source 
MySQL breaks GROUP BY syntax of standard SQL, and allows arbitrary columns with aggregate functions.
The ONLY_FULL_GROUP_BY stops this, instead raising an error. Since the SQL was originally designed
with this mode on, restricting the SQL broke the code in a few places.

Adding the extra group by clauses solves the issue without effecting query results.

These issues will be caught by MySQLTest in the future, since the issues could be reproduced by
enabling ONLY_FULL_GROUP_BY mode.

Affects issues:
- Fixed #2619
