In a subsequent patch, we'll further require that `fetch_refs()` must always be called before `consume_refs()` such that it can correctly assert that we have all objects after the fetch given that we're about to move the connectivity check. Make this requirement explicit by merging both functions into a single `fetch_and_consume_refs()` function.
