[FIX] sale_coupon: avoid duplicated checks/filters

Avoid filtering/checking the same condition multiple times on the same
records...

This allows to avoid n more fetch of all applicable coupon programs from
the database (because _check_promo_code is called on each program in a loop).

Also apply the date filter directly in SQL:
* The computation of inherited fields (_inherits) by the orm is intrinsically slow.

	The fields rule_date_from and rule_date_to checked in the _filter_on_validity_dates
	python filter are inherited from sale.coupon.program.rule model.

* Filtering recordsets in SQL is faster.
