Fix error message in incorrect rref.localValue() call (#31199)
Summary:
Closes https://github.com/pytorch/pytorch/issues/31198, see the issue for more details. We throw an error when `local_value()` is called on a non-owned rref, but the incorrect node name is printed in the error message. This PR fixes that and adds a relevant unit test.
