NeoFind Call erroneously attempting to connect to S3 on metadata only retrievals

[ifadams]

Describe the bug
Currently, the NeoFind call is erroneously attempting to retrieve an S3 object for metadata only retrievals when it should bypass any data retrieval path.

To Reproduce

Use a NeoFind call with a md_only type, and it should trigger an internal failure and eventually a transaction timeout.

Expected behavior

Bypass storage IO and just return metadata.

Additional context
This appears to be a problem sourced at using a default need_blob method within the neo4jfind class.
