Summary
Fixes #211.
When an existing cluster child is re-submitted with a blank ID,
BaseChildFormSet.save()previously kept the persisted child and attempted to add the submitted child again. This could result in anIntegrityErrorwhen the child model had a uniqueness constraint.This change removes existing children whose primary keys are not represented by the submitted forms before adding the saved instances.
