[brasero] Don't add the same file twice

[Philippe Rouquier <philippr src gnome org>]

commit fbff4873c306d4062361a4c41ba06f3aab0f1928
Author: Philippe Rouquier <bonfire-app wanadoo fr>

    Don't add the same file twice
    It can happen that a GtkFileChooserDialog triggers both activated and response callbacks adding the file twice.
    That happens when the first callback (because of an error, ...) calls gtk_dialog_run ().
