[FIX] stock: remove a useless with_user

- Before the change of `sudo` and `with_user` the code was non sense, it
was doing a `self.sudo(self._uid).check_access_rights('read')` which
was doing nothing.

But now with `with_user`, doing a `self.with_user(self._uid).check_access_rights('read')` breaks the
flag `superuser`.
Meaning that if the code was called using `sudo` it was bypassing the
ACL tests.
