gkodinov/kgeorge@macbook.gmz 565d495997 * Bug #20792: Incorrect results from aggregate subquery ...

When processing aggregate functions all tables values are reset
to NULLs at the end of each group. 
When doing that if there are no rows found for a group
the const tables must not be reset as they are not recalculated 
by do_select()/sub_select() for each group.
