max_combo is incorrect on certain beatmaps

[MillhioreF]

Examples: https://osu.ppy.sh/b/202965 returns a max combo of 1299 when the actual max combo is 1300, https://osu.ppy.sh/b/1090932 returns a max combo of 1031 when the actual max combo is 1032.

I'm almost confident that this is because the headless client used to generate this data is out of date and doesn't include the slidertick patch released about a year ago (I think fallback still has the old combo counts as well)

fun fact: oppai seems to be giving correct results 😛 (at least for those 2 maps)
