Title: Fixed Client to allow also empty passwords in HTTP Authentication.

RFC 2617 nor RFC1945 does not require that in HTTP Authentication, the password must be set. There are use cases (for example in some API keys) that only username is used and password is left intentionally empty.

This commit fixes Zend\Http\Client component to allow also empty passwords.
