orm: can't search inactive elements

[Xavier ALT]

Bugfix: Search inactive (active = False) elements will always fail

Even if args contain ['active','=',0], _where_calc function add an active test, leading to 'where active = True and active = False' SQL queries.

Steps to reproduce bug:
  - Mark some Partners as `inactive'.
  - Filter on Partners (Active = No)
    * No Result returned.

On PostgreSQL side, this will lead to this query (which obviously won't work):
   2008-10-30 15:53:43 CET LOG: instruction : select res_partner.id from "res_partner" where (res_partner.active = 'True') AND (res_partner.active = 'False') order by name limit 80
