The point-in-time lookups rely on some fetches from the durable catalog that currently use the _catalogIdToEntryMap cache since it assumes the durable catalog always looking up entries in the latest catalog. We need to make sure paths from openCollection that use the durable catalog for not-latest timestamp lookups actually scan the catalog rather than fetching from the cache.

Alongside this work, update the collection_catalog_tests relevant to PIT catalog lookups to always write to the durable catalog.
