Remove redundant needs war explanation code.

It is impossible to do "Conquer City" to a city that contains any units.
This means that the target city can't contain a unit from a nation the actor
isn't at war with. Remove action specific action not enabled explanation
code that is supposed to detect this.

See hrm Feature #643526
