It may return something which doesn't match font cache data structures any more
because the latter was changed (mostly to avoid glitches in compact_font_caches).

There was a slight confusion between font_list_entities (which operates
on vectors of font entities) and font_matching_entity (which should operate
on font entities). Hopefully the fix is almost obvious.
