Fix body ID bug saving SwfAsset outside modeling

Oops, if you saved `SwfAsset` outside of modeling code, the `item` field would be empty, and so `item.body_specific?` wouldn't happen.

This would trigger when you even just report a broken image!

Now, we always run the SQL query to check for that flag.
