The population of default values in INSERT SELECT was being performed twice. With sequences, this resulted in every second sequence value being used. With SELECT INSERT we remove the second invokation of table->update_default_fields(). This was already performed in store_values() invoking fill_record_n_invoke_before_triggers() which invoked update_default_fields() previously. We do need to return an error on duplicate values, so the ::store_values is extended to take the ignore option.
