Subject: tests: Add tests for changed-inputs on old-style inputs.

All these tests pass, because they only test the old-style input alists with
labels.

* tests/upstream.scm ("changed-inputs returns no changes",
"changed-inputs returns changes to labelled input list",
"changed-inputs returns changes to all labelled input lists"): New tests.
