Move Simulation to priority 3 helps to not block/delay immediateReindex
 on a scenario where everything is expanding. We use priority 3 to match
 what is used in SimulableMixin.updateSimulation and Delivery.localBuild

No need to generate simulation expand error

* copy all aggregate values
* expand source/destination project defined on the open order
* expand source/destination payment
* support Open Order Cell

- since-deleted ERP5 users
- coming from acl_users/zodb_users
Use a generic placeholder when the user is not allowed to see a
transition's actor.
