draft: create fewer intersection variations

Just like with venues, adding many alt names can create scoring
penalties(pelias/pelias#862) or
boosts(pelias/openstreetmap#507) that are
undesirable.

Unfortunately we don't currently have a great way to handle all
intersection searches without _some_ alt-names, but this change tests
removing some of them to see if we can stabilize scoring a bit.
