Subject: [PATCH] Tests: the io crate's hand-built saved models list their
 rounds, as format 7 records do

Model cache format 7 (f3cf0c4f3) records a `rounds` list in every saved model, and reading one
without it is refused ("saved model: rounds"), as is a model without any of its other lists:
the states, the preview and the thinned model all came back empty. The io tests' saved_model
and timeline_model wrote format-6 records, so six tests (the round trip, the repeated part
stored once, and the four too-big-for-the-file cases) read nothing. Their bodies are none made
by rounds: the list is empty, and every expectation stays as it was.
