Fix TokenFieldUiTest

Problem/Motivation

The tests on the 8.x-1.x branch are currently failing due to minor changes in core 11.2.x:

 Token Menu Ui Content Moderation (Drupal\Tests\token\Functional\TokenMenuUiContentModeration)
     ✘ Menu ui with pending revisions
       ┐
       ├ Behat\Mink\Exception\ResponseTextException: The text "Page obskpila has been updated." was not found anywhere in the text of the current page.
       │

       │ /builds/issue/token-3541207/web/core/modules/menu_ui/tests/src/Functional/MenuUiContentModerationTest.php:142
       ┴
     ⚠ Menu ui with unpublished content

The error in the output is:

Drupal\Core\Entity\EntityStorageException: An existing default revision of the 'menu_link_content' entity type can not be changed to a non-default revision. in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 815 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

And..
