When the list of values in the IN list of a single column contains
duplicates, multiple executors are activated since the assumption
is that each value in the IN list corresponds to a different partition.
this results in the same row appearing in the result number times
corresponding to the duplication of the partition value.
Added queries for the in restriction unitest and fixed with a bad result check.
Fixes#2837
Tests: Queries as in the usecase from the GitHub issue in both forms ,
prepared and plain (using python driver),Unitest.
