Describe the bug
Currently if you try to .attach() a model that has not yet been saved an error occurs.
This is specifically related to having foreign keys that are NOT nullable.

To Reproduce
with these models

class Profile(Model):
    __table__ = "profile"

   # user_id is a non nullable integer

    @belongs_to("id", "user_id")
    def user(self):
        return User
   
class User(Model):
    __table__ = "user"

    @has_one("user_id", "id")
    def profile(self):
        return Profile

attaching an unsaved record fails as the "user_id" is NULL

profile = Profile.fill({
    "role": "admin",
})
user = User.create({
    "name": "fred",
})
user.attach("profile", profile)
# throws a query exception "user_id" cannot be NULL

Expected behavior
Unsaved records should have the required keys linking them set during attach()
