    routeQuery: Require all filled points for valid
    
    Only consider query as valid if all points are filled.
    This avoids a case where adding a new destination using
    the context menu results in two requests being executed,
    first one with the previous places and immediatly one
    with the new point set to a place. This results in
    unnessesary API calls and a glitchy UX.
    
    Fixes #224
