Cards dealing wrong

In blackjack 1st card goes to player, 2nd to dealer, 3rd to player, 4th to dealer, but in engine it took 2 cards from end to player and 2 to dealer.


1. Mock cards:

```
    game.setState({
      deck: serializeCards('2h 3h 4h 5h 6h 7h 8h 9h 10h 11h 12h 13h'),
    });
```

2. Deal

**Expected:** Player / Dealer - 13h 11h / 12h 10h

**Actual:** Player / Dealer - 13h 12h / 11h 10h
