EMI: Fix the intro at cs_dock getting stuck in the PS2-version.

IsActorChoring takes different parameters in EMI than it does in Grim,
the original code was prudent enough about checking it’s parameters that
it actually ran fine, however the problem was that the argument that
said whether we should ignore looping chores was moved. This lets the
intro play the cut scene on the docks.
