[AutoDiscover] Use typehinting on PHP7

[bigfoot90]

Currently AutoDiscover is not using typehint feature from PHP7.
The main problem is that currently SoapServer is returning empty resposnse and status code 202 Accepted.

My service class:

class MyService
{
    /**
     * @param string $x
     * @return string
     */
    public function test(string $x): string
    {
        return $x;
    }
}

Expected

             xmlns:tns="http://localhost/api/My" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
