Description:
------------
When unsetting object property it unsetted from object then __get method of object is called while accessing it.

Besides property exists in all reflection objects (ReflectionObject and ReflectionProperty) but cause Fatal error while getting it.

Reproduce code:
---------------
<?php
class B{}
class A
{
	public $Var = null;
	public function __construct()
	{
		$this->Var= new B();
	}
	public function __get($name)
	{
		echo "get {$name}\n";
		if(isset($this->Var))
		{
			return $this->Var;
		}
		else
		{
			echo "Undefined variable\n";
			return null;
		}
	}
	public function __unset($nm)
	{
		echo "unset";
	}
}

$a = new A();
unset($a->Var);
$o = new ReflectionObject($a);
$p = $o->getProperty('Var');
Reflection::export($o);//Variable Exists
Reflection::export($p);//Variable Exists
var_dump($a->Var);//__get called 
var_dump($p->getValue($a)); //Fatal error
?>

Expected result:
----------------
$o = new ReflectionObject($a); 
has correct current instance properties or
$p->getValue($a) - will call __get method too and not cause fatal error.

Actual result:
--------------
Object of class [ <user> class A ] {
