Collection#last does behave correctly when [:id.asc] order is supplied

Read: Collection#last does NOT behave correctly when [:id.asc] order is supplied

Create a dummy model

class Foo
    include DataMapper::Resource

    property :id, Serial
    property :name, String  


Create dummy records

Foo.new(:name => 'alice').save; Foo.new(:name => 'bob').save

Observe the incorrect behavior

The following expression returns false as expected:

Foo.all(:order => [:name.asc]).last == Foo.all(:order => [:name.desc]).last # => false

But the following expression returns true; [:id.asc] is ignored:

Foo.all(:order => [:id.asc]).last == Foo.all(:order => [:id.desc]).last # => true
