Move action delay

[Kif11]

If I’m on a cell A going to cell B. While still on A I press UP the snake doesn’t go UP form A it goes to B first then UP.

This is happening because previous nextSnake doesn't receive update moves.

To fix:

const next = state => {
    return {
        rows: state.rows,
        cols: state.cols,
        moves: nextMoves(state),
-       snake: nextSnake(state),
+      snake: nextSnake({...state, moves: nextMoves(state)}),
        apple: nextApple(state)
    }
}

This is improve reaction to key presses and make game feels less sluggish.
