Ayush Chaurasia 32fdde23f8 fix: robust handling of empty result when reranking (#2313)
I found some edge cases while running experiments that - depending on
the base reranking libraries, some of them don't handle empty lists
well. This PR manually checks if the result set to be reranked is empty

## Summary by CodeRabbit

- **Bug Fixes**
- Enhanced search result processing by ensuring that reordering only
occurs when valid, non-empty results are available, thereby preventing
unnecessary operations and potential errors.

- **Tests**
- Added automated tests to verify that empty search result sets are
handled correctly, ensuring consistent behavior across various
rerankers.
