Update Java tests to match changes in API (#4535)

Commit cfeaf40ed6a9d4d7fec925352e30d2470a1ca567 renamed
`Result::Validity` and `SmtEngine::query()` to `Result::Entailment` and
`SmtEngine::checkEntailed()`, respectively. The commit did not update
the Java tests which lead to issues in debug builds with Java bindings.
The commit also adds a corresponding `NEWS` entry.
