Creepers that have been triggered do not cancel explosion when given NoAI tag

This is quite obscure but I have noticed that after a creeper has been triggered, you cannot disengage it by giving it the NoAI tag. I believe this is a bug because cancelling an explosion is part of a creeper's AI, seeing as you can disengage by immediately moving away even after it has started ticking down. So NoAI should naturally cancel any explosion that is waiting to happen.
