[BUG] JSONLD hook fails if any EDTF field exists without an RDF mapping.

[rosiel]

What steps does it take to reproduce the issue?

• Create a new EDTF field on a node, put some content in it, and load the node.
• Check the watchdog logs. You will see:
  Warning: Undefined array key "field_new_date" in controlled_access_terms_jsonld_alter_normalized_array() (line 65 of /var/www/html/drupal/web/modules/contrib/controlled_access_terms/controlled_access_terms.module)

code is here:

Line 65 in 4fc7177

foreach ($context['current_entity_rdf_mapping']->get('fieldMappings')[$field]['properties'] as $predicate) {
