[Items] Relic shield on Thresh does not execute minions below the health limit of the item

I would like to report a bug when playing thresh when you build relic shield (and any other evolutions of the item) it does not execute minions below the health limit of the item. This happens only when you lasthit a minion in the condition ad>minion's hp, so the relic shield passive is applied only for a half: it shared health and golds but you have to lasthit minions as if you don't have the item
