    Unref process_deferred_messages_source when clearing it
    
    Since g_source_attach adds a ref to a source and we keep the source stored
    in a global variable and, therefore, do not unref it after attaching it, we
    thus need to unref it when it is being destroyed and we clear the global
    variable.
