url-cookie.el: A cookie's localpart must not be nil

[Klaus Straubinger]

Some internet sites try to set cookies without specifying any local
part (e.g., "http://www.rad-net.de/";). The function
url-cookie-handle-set-cookie then calls url-cookie-store with nil as
its argument LOCALPART. But when this cookie is read again in function
url-cookie-retrieve, an error "Wrong type argument: stringp, nil"
occurs because it is expected to be a string.

My proposal is to make this tiny change:
