JOE should show a consistent tree

Current Situation
When adding orders or jobs that belong to a job chain the object tree becommes inconsistent as the objects are not shown as child at every job|order parent item.

Some examples for inconsitency:

• When loading a hot folder that have a job chain and assigned orders, the orders will not shown as childs in the order node that is assigend to the job chain. They are only listet in the table view. The will be show as childs in the tree when adding a new order.
• In the table view that is assigned to the job chains order the click to "new order" adds the new order to the order item but not in the table list view.
• When removing an order from the table list view that is assigned to the job chain assigned order the tree will no be actualize in the orders item that holds all orders (and viceversa)
• When adding an order in the all orders item and then assign a job chain the order will not be listed in the job chain ordes item.
• When changing a job chain by adding, changing or removing jobs, the jobchain job item will not be actualized.

Desired Behaviour
When adding an order or a job the tree should remain consistent.
