fall back to topPicksNearby if trending returns less than 10 results

I tested this out in a bunch of locations and feels like a better solution for now. Still works the same in San Francisco as the trending api almost always returns more than 10 results and now other places in the world that should have locations on map now show them all the time. Anyway, I feel it really doesnt matter if we use trending or explore for now since the map view does not show the number of people checked in at a location.
