[BUG]: Incorrect return type hints for Phalcon\Http\Response

[sergeyklay]

There is no restriction for content data type:

cphalcon/phalcon/Http/Response.zep

Lines 67 to 79 in d3e9463

	public function __construct(content = null, code = null, status = null)
	{
	/**
	* A Phalcon\Http\Response\Headers bag is temporary used to manage the headers before sent them to the client
	*/
	let this->headers = new Headers();
	let this->content = content;
	if code !== null {
	this->setStatusCode(code, status);
	}
	}

But Phalcon\Http\Response::getContent has to return string:

cphalcon/phalcon/Http/Response.zep

Lines 94 to 97 in d3e9463

	public function getContent() -> string
	{
	return this->content;
	}

The following code leads to a fatal error:

$response = new Response(['user' => 'jeremy']);
$response->getContent();

PHP Fatal error:
Return value of Phalcon\Http\Response::getContent()
must be of the type string, array returned in Unknown on line 0
