The new analyzer is enabled, but the old interpreter is used.

**Describe what's wrong**

The new analyzer is enabled, but the old interpreter is used. Simple MergeTree with simple `SELECT COUNT() WHERE col = val` query.

https://fiddle.clickhouse.com/40f154d8-c241-4927-a1de-e34f70faec7a

**Does it reproduce on the most recent release?**

Tested on 24.12.2.29.

**Expected behavior**

New analyzer should be used.

**Error message and/or stacktrace**
