This fix is incorrect, and it introduce new issues, in particular it
may breaks UNION queries w/o column aliases, i.e.:
SELECT a, b, c FROM (SELECT 3 AS a, 2147483647 AS b, 1048575 AS c UNION ALL SELECT -2, NULL, -2) AS js1 ORDER BY a

Projections
...
TODO (suggested by Nikolai)
1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies
3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)
Also need to figure out how prewhere works for projections, and
row_filter_policies.
