22d8e532ed Fix ORDER BY that matches projections ORDER BY 
In case of projection is seleted and it is comlete (all parts has such
projection) and ORDER BY matches projection ORDER BY, and
optimize_read_in_order=1 (default), then the sorting is simply not done,
because projections has separate plan, and so
InterpreterSelectQuery::executeOrder() -> SortingStep has
pipeline.getNumStreams() == 0 and it cannot do sorting.

Fix this, by adding sorting when creating plan for reading from
projections.

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.
