    httpclient: Simplify the clean up
    
    Now that the deprecated SoupSessionAsync has been replaced with
    SoupSession [1], the response callbacks are invoked in the next
    iteration of the main loop after soup_session_abort has returned. This
    means that http_client_check_response_cb is no longer called from a
    GCancellable::cancelled signal handler. Therefore, it's safe to
    directly disconnect from the GCancellable in the response callback
    without fearing for any deadlocks.
    
    This reverts commit b2f94098829232bcb8294d5cefee85d5b9368f2d.
