We perform uniqueness checks explicitly on the serializer class, rather
the using Django's `.full_clean()`.

This gives us better separation of concerns, allows us to use single-step
object creation, and makes it possible to switch between using the implicit
`ModelSerializer` class and an equivalent explicit `Serializer` class.
