Fix for #1390. The management of fetch_offset, position, and PartitionRecords is too complex! Nonetheless, I believe this change should fix the bug related to compacted topics. It may also improve compacted topic consumer performance when combined with max_records (previously it would have required sending a new fetch request if the max_records interval landed on a compacted message).
