[Gameplay] Graves - dashing immediately after attacking does not grant Sheen buff

Not that Trinity Force (or any Sheen item for that matter) is a common buy on Graves, but dashing immediately after attacking does not grant Sheen-like buffs.

The damage is not dealt on the attack prior to the dash, the buff is not granted, Sheen-item does not go on cooldown, and the damage is not dealt on the attack post-dash.

Does not seem to affect other champions, although I only tested Vayne.
