Spawned resistance agents to evac counted as neutral, thus are not saved and miss some debriefing logic

With roles they should be initiated as geoscape soldiers (with specific unit property) and spawn units based on generated properties. Thus they would avoid logic with resummoning civilians and all that, being recovered as natural soldiers.

They should get to the logic https://github.com/723Studio/OpenXcom_FTA/blob/6b3220c08de6908a52404902497a343b9e2863dd/src/Battlescape/DebriefingState.cpp#L1646
