#18387:

catalog:images:resize fails to process all images -> Possible underlying Magento/Framework/DB/Query/Generator issue

Ranged selects always miss the last range

Fix unit test. 11 batches expected to handle 105 items:

1: 1-10
2: 11-20
3: 21-30
4: 31-40
5: 41-50
6: 51-60
7: 61-70
8: 71-80
9: 81-90
10: 91-100
11: 101-105
