Clientside use - having to click back twice.

using config - 
```
  html5history: true,
  async: true,
  convert_hash_in_init: false
```

If I'm on ``/foo``
When I do ``router.setRoute('/foo/bar');`` 
The browser will move to ``/foo/bar#``
Then when I click back the first time I get to ``/foo/bar``
And only the second time go back to ``/foo``
