Object won't auto-approve as superuser

[silentjay]

Saving an object in the django admin logged in as a superuser was leading to these objects going into the Moderation Objects queue as pending, even with auto_approve_for_superusers = True explicitly.

I fixed this by adding a custom save_model() to the ModelAdmin for the model in question as suggested in the docs, even though I didn't have an existing save_model(). This looks like a possible bug to me, so putting this here just incase someone comes across the same issue.
