[CodeQuality] Skip non typed property no default value never assigned on SimplifyEmptyCheckOnEmptyArrayRector

[samsonasik]

The following code:

final class SkipNonTypedPropertyNoDefaultValueNeverAssigned
{
    /** @var array */
    public $property;

    public function isEmpty(): bool
    {
        return empty($this->property);
    }
}

as it has no default value, never assigned, and only rely on docblock which lead to check null value.

as AssignToPropertyTypeInferer service is used in TypedPropertyFromAssignsRector too, I add test for non-typed property has default value never assigned 75ae834
