fix: don't touch NemesisAbandonedRewards when spawning a lich

Because this can contain both grineer and corpus weapons, I think we should simply defer to the client's missionInventoryUpdate request in this matter.
This still leaves open the possibility of the client crashing between spawning the lich and finishing the mission, but that's rather unlikely, I guess.
