if an url is redirected, the redirect will not carry the querystring paramenters to the target url.

the frontend SA requires the ezdemo bundle.
test case:
1 - open some url my.site/object?config=foo in frontend
2 - in backend, rename the object to object2
3 - reload the url from point 1
4 - site redirects /object -> /object2, but the querystring is lost.
