Properly reset weapon accuracy on player respawn if sv_ready_restart_after_countdown...

Properly reset weapon accuracy on player respawn if sv_ready_restart_after_countdown is 1, thanks z411 for pointing out this bug

z411: "I think it seems to work as you expect because you are resetting the accuracies before the match starts, but once the players respawn accuracy_resend() which actually sends the stats is called in PutPlayerInServer() when they respawn. So the server is actually resetting the stats before it should, but sends them when they respawn."
