Changeset [aef47dcf937a5c9f150c50b73cffd9fa9eb64915] by Tim Harper

belongs_to polymorphic association assignments update the foreign_id and foreign_type fields regardless of whether the record being assigned is new or not.

fixes the following scenarios:

• I have validates_inclusion_of on the type field for a polymorphic belongs_to association. I assign a new record to the model's polymorphic relationship of the proper type. validation fails because the type field has not been updated.
• I replace the value for a ppolymorphic association to a new record of another class. The type field still says its the previous class, and the id field points to the previous record as well.
