SCRIPTS: Fix Conquest Lua Script

This had a bunch of NPC IDs off since the April update. This fixes the error on startup

This also had downstream effects that were mission blockers for CoP: because this broke the OnServerStart function before it finished processing, Old Prof. Mariselle's spawn location never got set, leaving players unable to finish the Sacrarium mission.
