Fixed #8070 -- Cache related objects passed to Model init as keyword arguments. Also:

Browse source 
* Model init no longer performs a database query to refetch the related objects it is passed.
 * Model init now caches unsaved related objects correctly, too. (Previously, accessing the field would raise `DoesNotExist` error for `null=False` fields.)
 * Added tests for assigning `None` to `null=True` `ForeignKey` fields (refs #6886).
