Fixes the failing Main workflow on stage after the merges of #216 and #221.

Changes

• tests/test_store_entity_keeps_jsonschema.py: _characteristic() passes subclass_of=[CHARACTERISTIC_TYPE] instead of subclass_of=[].

Rationale

• Main failed on stage at dce6069 (merge of fix: keep the stored jsonschema when store_entity regenerates it #216) and 8671be4 (merge of fix: select category templates from the schema allOf like the wiki #221). Three tests in tests/test_store_entity_keeps_jsonschema.py raised ValueError: subclass_of is required but not set from oold/model/v1/_descriptor.py:267.
• stage locks oold 2.3.0 since ae8cf92 (refactor: take the file controllers from opensemantic.core #214). The fix: keep the stored jsonschema when store_entity regenerates it #216 branch locks oold 0.16.2, where the empty list was accepted.
• The test helper set an empty list on purpose, so that the model does not resolve a superclass from a wiki. A fixed category IRI also avoids that lookup and satisfies the required field.
• Only test code changes. The production code from fix: keep the stored jsonschema when store_entity regenerates it #216 and fix: select category templates from the schema allOf like the wiki #221 is unchanged.

Tests

• Before the change, on stage: 3 failed, 12 passed in tests/test_store_entity_keeps_jsonschema.py and tests/test_store_entity_category_templates.py.
• After the change: make check passes, and make test reports 866 passed.
