    portal: Handle default object path in lookups
    
    If the service URI we are asking permissions for has the default
    object path, ensure we look it up with it being implicitly defined.
    This allows the following policies to work the same:
    
    dbus:org.example.Endpoint=*
    dbus:org.example.Endpoint:/org/freedesktop/Tracker1/Endpoint=*
