This optimisation prevents specific query paterns on stock table from
  reading a number of lines which is proportionnal to the number of operations
  present for a given criterion set.
  This optimisation requires:
   - new ZSQLMethod from erp5_core
   - 2 new catalog tables from erp5_mysql_innodb_catalog
   - inventories with new "full_inventory" property set to true
       full_inventory means that the user which did the inventory acknowledges
       there is no remaining resource besides what is present in the inventory.
Add test for this optimisation, disabled for now (required business templates
are not updated yet).
