[Bug] Duplicate images in Asheville, N.C. 1957 Vol. 1

[danvk]

Describe the problem

In the coarse of geocoding Asheville, N.C. 1957 Vol. 1, duplicates of some of the split panels popped up:

You can see the duplicate "33D [2]" images. There's also a duplicate of "33D [1]", it's just been georeferenced already. There are also duplicates of "3F [1]" and "3F [2]".

Expected behavior

I would expect one copy of each image.

To Reproduce

I wish I had an exact sequence. I don't think they appeared immediately after splitting, but I can't rule it out. I noticed the extra image after geocoding it, and it was still there.

Environment info:

n/a

Additional context

Hm, I'll look at this when I have a chance. It could be related to tickets like #308 but I thought that the underlying issue had been fixed, so I'm surprised to see this pop up again. Thanks for logging it.
