LP#1724029 Patron search API returns correct order

Avoid use of max_chunk_size in patron search API as it results in
streaming responses in the wrong order.  Use max_bundle_count instead,
which does not suffer from the sorting issues.  What's more, its purpose
and affect is easier to grasp in the code.

Bundle count is set to 5 so the API will begin returning results at most
5 patrons into the data fleshing process.
