The draft_timings parser sometimes assigns the first pick to the wrong team

[DMzda]

Current Behavior
The first pick is assigned to the same team as the second pick. This along with an incorrect/outdated draft side assignment in odota/web led to the draft sides to only be correct when the first pick was incorrect (see odota/web#2863 )

Example:
GET https://api.opendota.com/api/matches/6227419633

"draft_timings": [
        {
            "order": 1,
            "pick": false,
            "active_team": 3,
            "hero_id": 129,
            "player_slot": null,
            "extra_time": 130,
            "total_time_taken": 5
        },
        {
            "order": 2,
            "pick": false,
            "active_team": 3,
            "hero_id": 114,
            "player_slot": null,
            "extra_time": 130,
            "total_time_taken": 2
        },
        {
            "order": 3,
            "pick": false,
            "active_team": 2,
            "hero_id": 119,
            "player_slot": null,
            "extra_time": 130,
            "total_time_taken": 2
        },
        ...
]

See active_team above.

Expected behavior/code
The first pick's active_team should be 2.

Possible Solution
This is probably due to this line:

core/processors/processDraftTimings.js

Lines 49 to 50 in 461a5cb

	// update the team that had the first pick/ban
	draftTimings[0].active_team = ((sumActiveTeam % 2) + 2);

I don't currently have a good setup to test any potential fixes, but I may be able to in the future if needed.

Additional context/Screenshots
I wrote a small python script to identify broken matches:

You need requests and a /json subfolder to run it. The output looks like this:
