[Gameplay bug] Blitzcrank can grab ward debris

I was in a pvp game on Summoner's Rift, playing as . I casted my Q spell in the direction of an enemy that was killing my ward and, instead of grabbing her, I grabbed my own ward debris. The enemy team noticed the bug aswell.

Repro steps: 1- Join a game on Summoner's Rift playing as Blitzcrank 2- Level up your Q and place your trinket in front of an enemy champion 3- Let the enemy champion kill your ward while he stands behind it and, as soon as he's hitting it for the third time, cast your Q spell at his direction
