[BUG]: object return type hint leads to fatal error

[sergeyklay]

It seems object return type hint isn't properly handled by Zephir.

cphalcon/phalcon/Http/Message/AbstractRequest.zep

Lines 128 to 137 in 3049c86

	public function withRequestTarget(var requestTarget) -> object
	{
	if unlikely preg_match("/\s/", requestTarget) {
	throw new InvalidArgumentException(
	"Invalid request target: cannot contain whitespace"
	);
	}
	return this->cloneInstance(requestTarget, "requestTarget");
	}

At least for the following code:

$request = new Phalcon\Http\Message\ServerRequest();
$newInstance = $request->withRequestTarget('/test');

I get the following error:

PHP Fatal error:  Return value of Phalcon\Http\Message\AbstractRequest::withRequestTarget() 
must be an instance of NULL, instance of Phalcon\Http\Message\ServerRequest returned
in Unknown on line 0

As I can see object return type hint is just a stub and never had a real handler inside Zephir.

Fixed in 4.0.x branch
