- In test-environment mode, check for already existing file-hashes only in the "payload_aggregated" table, instead of the whole "payload" view. This way the investigation for false-positive docUrls is easier, as we avoid checking against the millions of "legacy" payloads. 

- Improve performance in production, by not creating the string objects for "trace"-logs.
