[BUG] Voracious Atakhan kill gold buff not being recorded

[JackWillz]

Bug Description
After slaying Voracious Atakhan, the +40G buff isn't registering in the data.

Problem Description
Killing Voracious Atakhan gives the player +40G on all future Kills. This is happening in-game, and can be seen in the Replay System, however the additional 40G is not recorded in any of the kill data.

Expected Result
The "bounty" value for CHAMPION_KILL events to be +40G above the standard value, i.e. 340G.

Actual Result
The "bounty" value for CHAMPION_KILL events is standard, usually 300G. The 40G is not recorded anywhere else, either.

Developer Impact
Incorrectly recording the amount of Gold gets prevents many features from working properly, and makes it much harder to determine which version of Atakhan was killed.

• Frequency: Every kill after Voracious Atakhan slain.
• Severity: Many Gold or Kill related features and statistics no longer are correct.

Preconditions
Any game when Voracious Atakhan was slain, and the team that killed it got a Champion Kill afterwards

Repro Steps

Example game: EUW1_7260615165
Atakhan slain by Blue side
No kills after Atakhan was slain include the +40G buff value, even though it did happen (as per the replay).

I think in general it would also be important to know which type of Atakhan spawned on the rift at all. As that in general holds important information about the game state and should best case be reflected as part of both the regular match data and the timeline data.
