Query results datasource: column not found with filter columns


Issue Summary

I can’t query a query using a filter column. There’s always an error of
Error running query: no such column: field

For instance, create a query like:
select 1 as idx, 2018 as ‘year::filter’;

You’ll get a table like this:

If you try to create a query on this table, you will never be able to query year=2018.
