attributes= does NOT set any attributes that are not included in the
hash. In this case it does not try to assign the value of :size.
As for not showing in the test log, I believe (but I'm not sure) that
AR will not run an SQL update unless attributes= changes the value of
any of the attributes it assigns. In this case, that is not happening,
so no query.
