Improve robustness of multiple renaming detections (and simultaneous hash format changes) of files in a row

[evhpomfort]

Improve robustness for:

• Renaming files multiple times (A1 > A2 > A3 > A4)
• Renaming files back and forth (A > A_Renamed > A)
• Renaming files and changing the hash format multiple times in a row
