Stop search has failures matching street intersections in certain cases

Example:

2.0.0p0 :017 > r21.inbound.stop_at("3520")
 => #<Muni::Stop tag="3520", title="26th St & Noe St", lat="37.7482699", lon="37.7482699", stopId="37.7482699", route_tag="24", direction="24_IB1"> 


2.0.0p0 :015 > r21.inbound.stop_at("26th St & Noe St")
 => nil
