In this commit we have changed the view sequence of attendees
list view opened through registration desk (`Select Attendee`
button) because registration is more likely to be used on a phone
or laptop at the entrance to register attendances. So we
need to show the kanban instead of list view.
For that we have created new action
`event_registration_action_kanban` and changed the sequence
as kanban first.
