In this commit we have changed some order of fields in
attendees form view, changes are listed below,
- moved `partner_id` field next to `event_ticket_id` and
made this field editable and trackable, this change had done because
currently this is the first field you see and it currently
looks like this is the person that's coming.
- moved `visitor_id` field below `mobile` field, so that even
in debug mode, Attendee Name is the "primary" field.
Apart from that right now if there are attendee data (name/email/phone)
and when we update the partner_id these attendee data will be erased
and updated as the new partner's information.
In this commit we are improving this, if there is any attendee data
it will not get erased while partner_id is updated. Attendee data
will get updated only if name/email/phone fields are empty.
