erp5_open_trade: Optimise calls of updateSimulation to not overcall the API

  This optimisation aims reduce the potential activity leak when over launching accross multiple activities/transactions the updateSimulation.
  SubscriptionItem: Add a method to call updateSimulation from sqldict activities
    updateExpandableRootSimulation allow launch activities in a safer matter and have lower calls.
