Explicitly exclude bytes from document requests

While investigating a separate issue, a few 500s from fdndb-api were spotted in the logs. Both around OrganizationDocuments and PeopleDocuments. On the fdndb-api side, there were a few corresponding 'Out of memory' errors. This likely means that fdndb-api is including the BLOB bytes in the response, which we don't need.

To avoid this, we should add includeBytes=false to our requests
