Add false eoc to Vampvirus checks in Xedra Evolved

[Maleclypse]

Summary

None

Purpose of change

Eliminate the roll remainder messages that continue on after the player has gained all the abilities for that stage.

Describe the solution

Ramza said that I needed to use the false_eoc array and since I couldn't find any examples of it in code I've attempted to make one real quick.

Describe alternatives you've considered

None

Testing

Tested and it works better than before.

Candlebury suggested replacing the ticking of the effect decay with an eoc inside the existing daisy chain similar to

"run_eocs": [
                      {
                        "id": "EOC_PERK_COMBAT_TEMPO_ADD_STACK",
                        "condition": {"or": [{ "u_has_effect": "tempo_counter", "intensity": 2 }, { "u_has_effect": "tempo_ready"} ]},
                        "effect": [
                            {"u_add_effect": "tempo_ready", "duration": "1 seconds"},
                            { "queue_eocs": "EOC_PERK_COMBAT_TEMPO_ADD_STACK", "time_in_future": [ "2 seconds", "2 seconds" ] }
                        ],
                        "false_effect": {  "u_add_effect": "tempo_counter", "duration": "2 seconds"}
                  } 
                ]
