[Bench] Reduce input cols number for fetch
To estimate output size of result query to allocate buffer we are running `count*` before some actual queries. This estimation requires only query body argumnets without `select` arguments, so this commit changes input_cols for `count*` query. Resolves: #574 Signed-off-by: Dmitrii Makarenko <[email protected]>
