[gnome-maps/wip/mlundblad/transit-routing: 5/23] routeQuery: Move routequery to the Application module

[Marcus Lundblad <mlundblad src gnome org>]

commit a4e8fcdebb9ea69ebd1e2d4d1cda1d7fb0ed139e
Author: Marcus Lundblad <ml update uu se>

    routeQuery: Move routequery to the Application module
    
    Let the Application module handle the route query singleton instance.
    This is needed so that the OpenTripPlanner module can access the
    query.
