Typo Fix[ci skip]
Newly instantiated STI records are not marked as dirty

Example:

    class Parrot < ActiveRecord::Base
    end

    class LiveParrot < Parrot
    end

    # Before:
    Parrot.new.changed? # => false
    LiveParrot.new.changed? # => true

    # After:
    Parrot.new.changed? # => false
    LiveParrot.new.changed? # => false
