[GAMEPLAY] Spoils of War bug with Kalista

When Oathsworn as a support with Kalista, the Spoils of War passive doesn't come into effect when attacking the same minion Kalista has within' the 1.5 second window that Kalista puts onto a target. Kalista still receives the gold she normally would have (as if Spoils of War has worked properly), however the support does not get the gold and a Spoils of War charge is not consumed [including no execution from the Spoils of War passive].

To reproduce, simply be Oathsworn with Kalista and have Face of the Mountain (or Relic Shield/Targon's Brace). Let Kalista attack a minion and attempt to last hit or execute the minion. Kalista should receive the normal gold, the Face of the Mountain wielder should not.
