[7.5 Store] Duplicate Methods in DB

> For some reason I've got a few duplicate method records in a Store
> package. The transcript shows a warning. How could that happen?
>
> I remember I was originally loading the package from a parcel and then a
> little later reconciling it with the Store package. I then wondered why
> there are so many "empty" classes listed in the package (i.e. no methods
> or shared variables, just the class name with empty protocols).
>
> After cleaning up the package in the image (removed several overrides)
> and publishing it, it still loads the old duplicate methods. It seems
> the dupes weren't removed from the DB.
>
> Is there a safe way to clean this up?
