Quaies mapped in OSM with bus_stop detached from platform impact matching quality

[hbruch]

In cases where a quaie is mapped in OSM with bus_stop detached from platform, like e.g. w45249788 and n9432197688 impact matching.

The large distance of the correct platform w45249790 reduces match rating, so the wrong match has higher priority:

Preferably, we would like to ignore the platform way and retain only the bus_stop node for matching, as platforms may give access to multiple stops and hence are less specific.
