Few-shot screening with zero-shot

[mmantyla]

Describe the bug
Few shot screening should work with just manual screening. Now it requires Zero-shot

To Reproduce
Steps to reproduce the behavior:

1. Use demo data https://github.com/EvoTestOps/AISysRev/blob/main/data/Demo_TimePressure_5_papers.csv
2. Manually evaluate single paper (exclude)
3. Try to start few-shot screening.
4. Click to exclude paper selection
5. One should be able to select the excluded paper but it is not visible.

However, if runs zero shot, does manual evaluation of single exclude then it works correctly.
