    pipewire-stream: Don't leak GSource's
    
    The pipewire loop is owned by the source, and failing to free it means
    pipewire will keep file descriptors open indefinitely.
    
    While we properly "destroy":ed the source, destroying it only removes it
    from the context, it doesn't destroy or unref it. To also free it, we
    also need to unref it.
