[Gameplay] Master Yi Alpha Strike resets Dragon, making it knockback again and heal.

There was a thread a while back about this but it never got fixed (http://boards.na.leagueoflegends.com/en/f/LqLKtMpN/d/OLKUz06A?comment=0007 Been in the game since Preseason 5). It makes early dragon solos much harder than they should be since you keep getting knock backed over and over while the Dragon even regains some of it's health as if it's completely left combat.
