    uris: Accept OSM location URLs without ?
    
    Sometimes shared URLs pointing to a location in OSM
    is on the form https://www.openstreetmap.org/#map=...
    
    E.g. encoding the parameters as part of the path
    instead of a query.
    
    Accept both variants, and add an additional test case.
