cityManager.GetCity() with removed meeple

[Kaszana102]

City manager doesn't update its meeples in the cities, which causes an error when trying to look them up in fields. If the city has been finished, a city manager doesn't remove meeples from the manager. Thus in the end, during the final scoring, when fields are scored and they ask the city manager for a city with a certain feature which used to have meeple, the city manager returns nil as it also checks meeple existence.

Solution: either update city manager meeples while scoring cities or omit checking meeples in CityManager.GetCity()

I think that ignoring the meeple in lookups (by unsettling the meeple in the keys) would be cleaner out of the proposed two solutions.
