Prevent final variables from being accessed by orders

Current Situation

• For workflows that use final variables when modifying the order (modification of start time or modification of variables) the web service returns final variables available with the JSON orderPreparation node.
• As a result the GUI adds such variable when submitting orders which raises errors as no final variables can be added to an order that is submitted to a Controller.

Desired Behavior

• The API should prevent final variables from being available. Such variables represent constant values that should not be made available by the API in order to prevent them from being submitted with an order.
