Add COMMAND COUNT test to cover reply-schemas-validator test (#11971)

Since we remove the COMMAND COUNT call in sentinel test in #11950,
reply-schemas-validator started reporting this error:
```
WARNING! The following commands were not hit at all:
  command|count
  ERROR! at least one command was not hit by the tests
```

This PR add a COMMAND COUNT test to cover it and also fix some
typos in req-res-log-validator.py
