Fixed issue with ordering of non-app token windows

We tried to fix this issue in I83357975c87c704af9d0702c939ca99984462365
but the fix introduced other problems. So, we are going to have sys-ui
create a separate binder for object for each type of window it adds.
Long term we want to allow one binder object to map to multiple window
tokens on the same display in window manager.
