    Fix crash setting web app title without hostname
    
    We probably shouldn't allow creating web apps for URIs without hostnames
    at all, but regardless, we should always check the result of
    soup_uri_get_host() because it could return NULL. Here we actually do
    that check, but don't guard enough of the code with it.
    
    Fixes #618
