Subject: [PATCH] keep the two summoners in the opening state

LogicBattle::resetSimulatedManaTimers reads both leaders out of the
battle at +96 and +104 and calls a virtual on each without a null check,
so an opening state with no leaders segfaults inside LogicGameMode
::decode before anything else happens.

so the opening state carries the two king towers and nothing else. they
are the objects that cannot get a model - the battle screen, and with it
the listener, does not exist yet - and they are also the pair the hud
caches at [SpellButton+0x1d0], so they are exactly the objects that must
not be replaced later either. everything else, princess towers included,
now arrives after the screen is up.
