Fix refcnt for unused MergeTree parts in SELECT queries
...
Before this patch SELECT queries hold parts even if they were not
required by select (had been eliminated by partition pruning).
This defers removing parts if you have long running queries.
This had been introduced in #23932 , with introduction of
StorageSnapshotPtr.
