Add full ontology declaration to phenio-test.owl header

...add an annotate to ensure a full declaration gets added.

phenio-test.owl doesn't get a full ontology declaration added to its header.
This isn't generally an issue until we try to transform it to obojson, at which point it isn't valid.
The declaration can be added with a ROBOT annotate command, at least to add IRIs.

You may be able to achieve this with --copy-ontology-annotations: https://robot.obolibrary.org/extract#extracting-ontology-annotations

Oh wow, I didn't even notice that flag before. Thanks @matentzn - will try that first.
