Fixed LP bug #668644.
The pushdown condition for the sorted table in a query can be complemented
by the conditions from HAVING. This transformation is done in JOIN::exec
pretty late after the original pushdown condition have been saved in the
field pre_idx_push_select_cond for the sorted table. So this field must
be updated after the inclusion of the condition from HAVING.
