to_ary() private

Under Ruby 1.9, Array#flatten will call #to_ary (recursively) on each of the elements of the array, and then rescues from the possible NoMethodError. If those elements are ActiveRecord::Base’s, then this triggers the various method_missing’s that we have, which significantly impacts upon performance.

So we can avoid the method_missing hit by explicitly defining #to_ary as nil here.
