[GAMEPLAY] Ward deaths detonate Teemo shrooms

While I was playing Teemo, there were multiple situations where my shrooms would go off with no enemies near and just the "invulnerable" text appearing whenever the poison WOULD proc. At first I didn't know what was going on. However, when my ally walked through a bush, the shroom detonated, and a ward corpse appeared. Another instance, I had thrown a shroom into a bush, only to find an enemy's farsight ward. As soon as I destroyed it, the mushroom on top of it detonated.
