Fixed MDEV-5617: mysqld crashes when running a query with ONLY_FULL_GROUP_BY

Problem was that we used cache_table in some cases where it was not initialized

mysql-test/r/func_group.result:
  Added test case
mysql-test/t/func_group.test:
  Added test case
sql/item.cc:
  Don't use cached_table if not set
sql/item_sum.cc:
  Don't use cached_table
