Summary0003373: crash when exiting before countdown finished
DescriptionWhile investigating 3371 (which i was unable to reproduce on 91.0) i found that spring crash if you exit before countdown finished.
This is because the AI is not created properly until game start and shutdown will try to destroy the non-existing AI since the AI has an id before start:

void CEngineOutHandler::SetSkirmishAIDieing(const size_t skirmishAIId) {
    SCOPED_TIMER("AI Total");

    try {
        id_skirmishAI[skirmishAIId]->Dieing();
    } CATCH_AI_EXCEPTION;
}

Map id_skirmishAI above is empty so we get a new NULL pointer entry.
Steps To Reproduce- start spring
- setup Player vs NullAI game (i used BA 7.72)
- press "Test the game" and exit (Alt+F4) before countdown finished
Additional InformationThis crash started at commit 6b2fd94621d91cfd528e2021bc36a295db00ee72, not sure why though.
I attached an ugly fix for this which checks for null-pointer but i think we need a better fix.
