    Do not unset sensitivity mistakenly in gtk_widget_set_state_flags()
    
    together with commit 8903615a34, this finally fixes bug #640282.
    Insensitivity is handled separatedly in _gtk_widget_update_state_flags(),
    but the insensitive flag is mistakenly unset afterwards if clear is TRUE
    in gtk_widget_set_state_flags().
