Saving doesn't work when pk is UUID?

[Ox54]

Describe the bug
Saving a model (.save or .create) who's pk is UUID results in the following error:

NoMatch: Instance was deleted from database and cannot be refreshed

To Reproduce
Steps to reproduce the behavior:

class Tenant(ormar.Model):
    ormar_config = get_engine().ormar_config.copy()

    id: uuid.UUID = ormar.UUID(
        uuid_format="string",
        primary_key=True,
        server_default=sa.text("uuid_generate_v4()"),
    )

    # id: int = ormar.Integer(primary_key=True, autoincrement=True)

    name: str = ormar.String(max_length=255, unique=True)
    address: str = ormar.String(max_length=255)
    city: str = ormar.String(max_length=100)
    state: str = ormar.String(max_length=50)
    zip_code: str = ormar.String(max_length=20)

tenant = Tenant(
    name="Blueberry",
    address="123 Main St",
    city="San Francisco",
    state="CA",
    zip_code="94105"
)

tenant = await tenant.save()

tenants = await Tenant.objects.all()
tenants

Expected behavior
The model saves without error.

Hey there - the issue isn't to do with ORMAR, but the server default you're using - doing UUID to text to UUID does some weird stuff, so I've tended to avoid that. What I do is use a default factory instead, like so:

id: uuid.UUID = ormar.UUID(primary_key=True, uuid_format="string", default_factory=uuid.uuid4)

Give that a go and lemme know how it goes.
