Update test_document_model.py

* fix(search): resolve index-write permissions and effective content in bulk

Add WriteBatch.add_or_update_ids() and use it in bulk_update_documents
and trash restore, cutting index writes from ~8 queries per document
to a constant handful per batch

* Always these new ones with xdist, try a better condition
