Malcolm Tredinnick 53da1e4794 Fixed #9649 -- Better error handling in model creation. 
Previously, you could explicitly assign None to a non-null ForeignKey
(or other) field when creating the model (Child(parent=None), etc). We
now throw an exception when you do that, which matches the behaviour
when you assign None to the attribute after creation.

Thanks to ales.zoulek@gmail.com and ondrej.kohout@gmail.com for some
analysis of this problem.
