> The optimize method may change the MatchCode from SEEK_NEXT_COL/SEEK_NEXT_ROW
> to SKIP. But it still pass the next cell to ScanQueryMatcher. It will get
> wrong result when use some filter, etc. ColumnCountGetFilter. It just count
> the columns's number. If pass a same column to this filter, the count result
> will be wrong. So we should avoid passing cell to ScanQueryMatcher when
> optimize SEEK to SKIP.
