FRED2: Updated ship team is not considered for ship AI orders in Ship editor

[Shivansps]

This is a minor inconvinience, but ill report it anyway.

Lets say, you have a ship that is by default on the friendly team:

1. Open ship editor
2. Change team to hostile
3. add ai orders to attack a ship in the friendly team

Fred will complain about you assigning it to attack same team, because it is not using the team change you just made.

This also means it will ignore cases were it should give an error, like in the previous example, add an order to guard an "friendly" ship. Until you try to save the mission.
