use_item_on: a placed jukebox keeps its record and has_record

JukeboxBlock.setPlacedBy reads the placed item's block_entity_data and sets
HAS_RECORD when it carries a RecordItem, so a Creative pick of a jukebox with a
disc keeps the disc when it is placed. The behaviour is on main; no harness case
pinned it.
