Lighttable preview & thumbnail images not updated after history change

[pozix604]

Describe the bug

Lighttable preview and thumbnail images do not reflect current state of image after a prior entry in the history list has been selected.

Steps to reproduce

1. Open image in darkroom
2. Crop a few times
3. Exit darkroom, verify preview/thumbnail reflects latest image state
4. Open image in darkroom
5. Choose an earlier crop in history
6. Exit darkroom, thumbnail image is not updated
7. Open image in darkroom
8. Choose a crop later in history but prior to the most recent
9. Exit darkroom, thumbnail image and previews are not updated

Expected behavior

If a user selects a previous history entry, it would stand to reason that the user wants that specific edit. That is the "current" image even though it is not the most recent entry in the history. The thumbnail and previews should reflect this.
