The recursive tika response lists the file first, then its embedded
resources (cover art, thumbnails, the clip appended to a motion photo).
The loop applied getImage/getPhoto/getLocation/getAudio/getLivePhoto to
every part, so an mp3's embedded cover art leaked a 200x200 image facet
onto the track (and an embedded EXIF image would leak photo/location).
Read those facets from metas[0] only, like the video facet already does;
the loop now only concatenates title/content and detects the motion
photo clip.
