Update causes all caravans to stop moving

[CIVITAS-John]

My personal fix is to add a check on Scout.cs, line 358 and 368:

if (this.WarSettlementComp != null)

<= This check prevents null reference exceptions and allows my game to continue..

For Trader.cs, line 352:

I added a check for rwsc.parent:
if(rwsc != null && rwsc.parent != null && rwsc.parent.Faction != this.Faction && !tradedWithSettlement)

Im thinking it might be a good idea to commit this because there were other complaints about this on the steam page
