* Reassign the "event" tour to a classic test
- Only the "event_tour" that starts from the Event App should be kept from a
user perspective.
- The "event" tour that launched itself once upon installing the Event App
from the Website (Website App) and only covered the front-end part of
the event creation will now only be kept as a classic test tour.
- This tour is renamed "website_event_tour" instead of "event" for
disambiguity with the other tour called "event_tour"
* This tour is now only intended to be used as a test, and as such, is moved
to `tests/tours`
