fix: update tests and changelog for AssetVersion refactoring

- Add test cases that validate fix for KeyError when downloading photos with
  --size adjusted --size alternative options (issue #926)
- Update test expectations to match corrected behavior after refactoring
- Fix AssetVersion constructor calls in remaining test cases
- Update CHANGELOG.md to document the bug fix

Tests now properly validate that missing adjusted/alternative versions
fall back to original version without throwing KeyError exceptions.
