Fixed bug #62500 (Segfault in DateInterval class when extended)

[reeze]

https://bugs.php.net/bug.php?id=62500

When accessing properties before DateIntervl initialized will cause segfault.
other functions checked this situation but left property getter and setter function.

Hi:
I am sorry to say, your fix is wrong.

1. thinking of:

class Crasher extends DateInterval {
public $y = "xxx";

  public function __construct($time_spec) {
              var_dump($this->y);
  }

}

your fix will trigger a warning and output a NULL, it's totally wrong.

the same issue also exists in the write context.

1. there will be a memleak of your fix when the key is not a string.

I will make another fix , thanks
