Upload: Add duplicates to selected albums as well

[kardianos]

As a user, I would like to add a photo set to an album, even if they are already in the system. Theoretically I could find them within the system and add them, but that can be tricky to find them if there is sufficient entropy.

In internal/photoprism/import_worker.go, we have a few loops and Ifs that import the logic. Of importance here is imp.DestinationFilename and entity.AddPhotoToAlbums. If DestinationFilename fails, no further processing is done. Which is what you normally would want. However, In this case, I would still like to add it to the photos.

Allowing this would require refactoring this function a fair amount and would probably be in two parts: (1) refactor (2) allow adding to album pre-existing photos.

I can make this change and add some unit tests probably, but I would want to get approval for the concept first.

This has been released. You may test it using our latest Docker image.
