Player#matchData#deaths inconsistency on early rounds

[vctrkang]

After "round_announce_match_start", in the "round_officially_ended", using Player#matchData[currentRound]#deaths is not accurate.

For example, on pistol round, all the kills are tracked properly, but the deaths is always 0.
In fact, it's actually stored in round 12.

By the end of the match, it seems like it's fixed, but during each "round_officially_ended" event it's wrong.

Example matchStats at round 1 (demoFile#gameRules#roundNumber starts at 1 for the first round).
