Fix intersectionsCross3Test test for MVT tiles

soundscape-backend was providing slightly different GeoJSON than MVT for
paths marked as pedestrian. This change fixes that so that instead of
being `highway=path` they are tagged `highway=pedestrian`. There may be
other tweaks needed here too, more testing required.
