#105 - array no multiline whitespace

[kamilpiech97]

This should close #105.

Actual:

    public function getArray1(): array
    {
        return [

        ];
    }

    public function getArray2(): array
    {
        return [1

        => 2];
    }

    public function getClosure(): Closure
    {
        return fn() =>
            [];
    }

Expected:

    public function getArray1(): array
    {
        return [];
    }

    public function getArray2(): array
    {
        return [1 => 2];
    }

    public function getClosure(): Closure
    {
        return fn() => [];
    }

Fixed in composer.json scripts for running tests. From --colors always to --colors=always.
