Title: Prevent prepare from persisting an instance for a related OneToOneField

This change fixes `mommy.prepare` so that it won't persist an instance when there is a OneToOneField in the model. This problem and the solution is defined in issue #153 by @bahaddinyasar

It was already the case for ForeignKey fields, this is just an addition for the OneToOneField.
