erp5_commerce puts (temporary) persistent objects in session, that is not possible with Distributed Ram Cache.

so that we can use Distributed Ram Cache as the backend of the session cache.

This is required for ERP5Site_checkDataWithScript script (erp5_core BT).

This is not a new feature, this behavior is compatible with the old caching
implementation that was using inventory_stock table.
In other words, this brings backs the backward compatibility in inventory
caching.

(This commit fixes the incomplete tests that was reverted just before.)

Needs more tests.

This reverts commit 74db4d39.

omit_balanced_accounts was always displaying 1
omit_empty_accounts should not exist

To display the list of possible accounts we include validated nodes and  nodes that have been previously used on accounting movements. We include 2, because we want the user to be able to issue a report on a node that has been used in the past and is now invalidated.

The problem with this approach is that such query is very slow, when there are a lot of Movements.

Then, with the commit only validated accounts will be considered

The script ERP5Site_getWorkflowStateItemList that receives the portal type and the state variable (simulation_state/validation_state) as parameters and it will returns the states for the workflow chained to the portal type
