MDEV-10500 CASE/IF Statement returns multiple values and shifts further result values to the next column

Browse source 
We assume all around the code that null_value==true is in sync
with NULL value returned by val_str()/val_decimal().
Item_sum_sum::val_decimal() erroneously returned a non-NULL value together
with null_value set to true. Fixing to return NULL instead.
