Improve test points: flaky and verbose

* Make test point less brittle

`tazureChat/generateWithStructuredOutput` has somewhat frequent spurious failures of this type:

```

```

Rather than trying to add more and more valid alternatives, it is probably better to relax the requirements a bit.

* Make test less noisy

`texampleTests/testAnalyzeTextDataUsingParallelFunctionCallwithOllama` was lacking the `evalc` against noise cluttering the output.
