Fix M02 softlock from autosave

[Caenen]

I encountered a softlock during my playtesting of 0.7 after reloading in Mission 2 from Autosave (the one after shooting up Cosmo). Because King is respawned at his original entry position near the New York Gate, but the player is immediately near the trade lane, they can arrive at Pueblo station and shoot down the first Rogues well before King hits a trigger that depends on him on the final trade lane ring. This results in a soft lock where the mission cannot progress.

I will track down the best way of adjusting the script for this case. Reloading from this autosave is likely rare for a new player (unless they are as trigger-happy against neutral cosmo as some experienced players), but triggering the soft lock from that reload is actually very easy.
