Respect region name when processing domain URL

When deprecating the use of management_url from service_catalog we
updated the management_url setter for the project scoped token, however
we missed the domain scoped token case.

There is actually nothing we can do here to test this scenario as the
backwards compatibility code that was installed handles this for us and
there is no problem, however we should not be internally relying on
deprecated code.

Remove test_print_{dict,list}_unicode_without_encode

These tests do not really make sense: they expect the strutils.safe_encode()
method to fail for some reason.
