when semijoin=on When setting the aggregate function as having no rows to report the function no_rows_in_result() was calling Item_sum::reset(). However this function in addition to cleaning up the aggregate value by calling aggregator_clear() was also adding the current value to the aggregate value by calling aggregator_add(). Fixed by making no_rows_in_result() to call aggregator_clear() directly. Renamed Item_sum::reset to Item_sum::reset_and_add() to and added a comment to avoid misinterpretation of what the function does.
