[gedit] Connect to ::selection-done to destroy the GeditNotebookPopupMenu's

[Sébastien Wilmet <swilmet src gnome org>]

commit 623f95466671f7b0a8e8aec746809b3ae52842b3

    Connect to ::selection-done to destroy the GeditNotebookPopupMenu's
    
    It's better than calling g_object_unref() directly after
    gtk_menu_popup(), ::selection-done has more guarantees to work.
