TicketQuery with format=progress doesn't show progress when no matched ticket (part of #13474)

Now, with the implemented fix, a progress bar for a query that yields no tickets looks as follows:

It is definitely better than a python error message but it does not look especially pretty. One could try to display an empty progress bar here instead?

I would not opt for a "No Results" message because when using format=table we get an empty table and not "No Results". An empty progress bar would be more consistent.

Open to suggestions! What is the expected behavior? Or would handling None values in templates/progress_bar.html be more preferable?
