I don't want to feed you incorrect information here so hopefully
someone will confirm.
create, insert and populate do not need to be supplied a id  (where id
is a Primary Key, with or without auto-increment). That is taken care
of by DBIx::Class::PK::Auto. You use id generally for search/find.
Omit the id from your hashref.
