JVM IR: do not serialize metadata for actualized optional expectations

Optional-expectation annotations which have an actual counterpart should
have never been serialized to the kotlin_module's proto. See for example
the original (correct) implementation in the old JVM backend in
`PackageCodegenImpl.addDescriptorToOptionalAnnotationsIfNeeded`.
