Success reported when output folder does not exist

A user was attempting to validate with their openmw.cfg located on OneDrive. If the input of --cfg exists, the program seems to assume success:

C:\Users\miasp>"c:\morrowind\openmw-validator\openmw-validator.exe" --cfg "c:\Users\miasp\OneDrive\Documents\My Games\OpenMW\openmw.cfg"

2024/03/13 23:52:10 ERROR: open C:\Users\miasp\Documents\My Games\OpenMW\validator-2024-03-13-235210.log: The system cannot find the path specified.
Validation completed, log written to: C:\Users\miasp\Documents\My Games\OpenMW\validator-2024-03-13-235210.log

The user did not specify an --out and the default path did not exist; no .log file was generated.
