Fix ProductCreateWizard on run_dialog

The fix before broke ProductCreateWizard. The SearchEditor's run_dialog sends
model and visual_mode too, and ProductCreateWizard is not prepared to receive
them (and don't want since it doesn't make sense).

Receive them on *args and **kwargs so they can be ignored
