Fixed #34779 -- Avoided unnecessary selection of non-nullable m2m fields without natural keys during serialization.
By using `select_related(None)` instead of `select_related()`, the
unnecessary joins are completely avoided. Note that the current tests
already covers the change, when the field is not `null=True`.
Regression in f9936deed1ff13b20e18bd9ca2b0750b52706b6c.
