Executions dont switch owner (#326)

when an building is taken over by another player the execution for it
doesnt change its owner this makes it so when a sam is captured it tries
to intercept your own nukes and doesnt intercept the ones by the
previous player

this change makes executions of buildings automaticly switch their owner
