test(azure): expect the object root the passthrough now normalizes

The additional_tools normalizer from the previous commit also runs on
the Azure passthrough, so a schema written as {} in the fixture ships as
{type:"object"}. This test is about namespace lowering in the tool name,
not about the schema shape, so the expectation is updated rather than
the normalizer narrowed.
