Vi auto-attack reset bug: very frustrating, can severely impact gameplay.

Steps to reproduce:

1. Be near minions that are killing each other.
2. Find a minion that is about to be killed.
3. Press E
4. Auto-attack the minion with the right (wrong) timing so your attack would land after it has died.

Results:

1. Auto-attack fizzles and leaves Vi with the charge still on her for her next auto-attack (this isn't necessarily a problem, but it might be if it is unintended)
2. Vi gets locked out of auto-attacking for several seconds, and is unable to attack anything for that duration.

Please fix this, it has been very frustrating and I've lost trades and fights in lane and jungle because of hitting a minion like this and then not being able to trade auto-attacks with opponents.
