    soup-message-queue: hold a reference to the async context
    
    This will ensure that the GMainContext is not freed at least until we get
    rid of the queue item. This was causing crashes when synchronously
    retrieving resources in WebKit as it uses a different GMainContext for each
    of those synchronous requests.
