[Gameplay] Gankplank destroying a barrel chain adds to his CS count (Minor Bug)

Gangplank's CS Counter goes up by 1 each time he destroys a barrel chain that is connected by a gunpowder trail (doesnt matter how many barrels are in the chain it is always 1)

No gold is given for the barrels so there is no actual effect on the gameplay but it messes with the statistics of that game
