gdbus: Don't include just added interfaces in GetManagedObjects

If we received a call to ObjectManager.GetManagedObject we should not
include in the response the interfaces in data->added. This is because
it's not guaranteed that those interfaces will trigger an
InterfacesAdded signal, which is the case if the interface is removed in
the same mainloop iteration.
