If you register online on a free event, there is an
access rights error when trying to download the ICS file
if you are connectd with public user.
`if not event` part is pointless, if event cannot be resolved,
@http.route would return a 404 anyway.
`if not event.registration_ids` does not make sense from a
functional point of view: there is no problem in generating
an .ics file for a public event that has no registrations (yet)
and the button we use to generate the .ics file is displayed
after the registration anyway.
