Remove "Die a glorious death" from the objective pool for Double Agents

Created by: Exxion

Come on, it's just dumb. If your target has a die objective, you can get greentext without doing anything at all. If you have a die objective, you can use stupid cheap piss tactics such as the tactic I should really stop using in this situation, parapen and self-explosive implant (or just the implant if you are confident enough in your robustness) to accomplish both your objectives within five seconds. I mean I guess you could do the latter on a normal Traitor round, but the die objective is so rare in Traitor rounds it doesn't matter.

Honestly, Double Agents needs a lot more than just this to be any good, but this is the most glaring issue I have with it.
