[GAMEPLAY] Quadra kills not displayed correctly

Server: EUW

Type of Bug: Interface bug (?)

Description: If you get multiple kills, you get this in-screen notification that says the amount of kills and has a certain amount of bars in the background, each representing a kill. However, since couple patches ago, quadra kill is not displayed correctly anymore and is shown as double kill. I think sometimes triple kills are also displayed as double kills.

Video / Screenshot: Just watch this Cowsep montage. You can see the correct order right in the beginning (first clip) of the video, and the current state directly afterwards

Steps to reproduce: Play a game, go ham and kill four people.

Expected result: You see one bar for a single kill, two bars for a doublekill, three bars for a triple, four for a quad and five for a penta

Observed result: You see one for the single kill, two for the double, three for the triple, two for the quad and five for the penta

Reproduction rate: Pretty sure it's 10/10

System specs: Irrelevant

I know it's a minor bug but this and the spectator bug where you can't press "c" on champs anymore irks me a lot.
