sparse: drop the useless wrapping of `dirstate.set_untracked`

The code of the wrapper only act in the case where the file is not tracked, so this has not effect for `untracked`. In addition the message explicitly mention `add` of a file and no test are breaking if we drop this.

So we drop this for simplicity and cleanup
