Fix replay view of discard pile.

In the replay mode the view object is not serialized to JSON before
viewing, so we cannot rely on the JSON representation dropping any
properties with the value "undefined".

Don't use (property in object) to check if something is undefined.

Initialize game.discard pile in on_setup as well.
