[Php71] Skip with If always array on CountOnNullRector

[samsonasik]

Given the following code:

final class SkipWithIfAlwaysArray
{
    public function run($a, $b)
    {
        $data = [];
        if (! $a) {
            $data[] = $b;
        }

        $data[] = count($data) !== 0 ? 'a' : 'b';
    }
}

Currently produce:

+        $data[] = (is_array($data) || $data instanceof \Countable ? count($data) : 0) !== 0 ? 'a' : 'b';

which should be askipped as always array.
