[OMP] Review ONIX export for calls to get localized data

[asmecher]

Describe the bug
The ONIX plugin has calls to getLocalized... functions, which will get localized data based on the exporting user's current locale.

Metadata exports shouldn't depend on the current locale. In cases where the exporting standard doesn't support multilingual data, it's better to rely on the publication's primary locale ($publication->getData('locale')) in deciding which language to include.

@bozana could you review whenever you're able? There's one issue I'm seeing that maybe we can take a look at together and I've made a note in the PR.

Will forward-port once ready.
