[GAMEPLAY] Smite + turret = executed

So I noticed if an enemy player is going to be executed from a turret and you smite them, you do not get the kill. It counts as "executed".

I experienced this playing purple side on top turret as Warwick vs Nami. I smited her, then the tower hit her once or twice to finish her off. I didn't receive a kill (or assist). I asked her what it said in the death recap screen and she said it showed me as having an assist.

Should be easy to replicate, just have someone run into tower and only take dmg from turret and an enemy champions smite (smite didn't get the killing blow).
