[Gameplay] Yorick's mistwalkers cause weird message in chat

Yorick's mistwalkers cause following or similar message to appear repeatedly in the chat without brackets "-- Respond to Aggression -- 1 with aiState7" my thoughts on this one is probably that somehow a comment in the code got somehow inside the console print when you devs where testing something. I myself saw this appear last time in the patch 6.21 but didn't see it in "bugfixes" section on this patch so i decided to post it now when i recalled seeing it.
