[GAMEPLAY] Warwick Bloodhunt passive doesn't trigger after respawn

After Warwick has been killed and respawned or after he has just learned his W, he does not sense any champions (unless they are manually detected by hitting W) that are under 50% health until they take damage again or they recross the 50% threshold.

1. Die as Warwick and respawn.
2. If an enemy is under 50% health, they aren't blood hunted until one of the above events occur.

This is reproduceable 100% of the time.
