Bug 20144: [sql_modes] Fix GROUP BY clause in GetBasketsInfosByBookseller

This need to be tested from the interface!

Fix for:
'koha_kohadev.aqbasket.basketname' isn't in GROUP BY

t/db_dependent/Acquisition/GetBasketsInfosByBookseller.t

We need this group by.
We should not need to list all fields, from mysql 5.7 doc:
https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html
"The query is valid if name is a primary key of t or is a unique NOT NULL column. In such cases, MySQL recognizes that the selected column is functionally dependent on a grouping column. "

However, MariaDB did not implemented yet:
