Fix test performance of Drupal\Tests\content_translation\Functional\ContentTranslationMetadataFieldsTest

Learned more since last year so will pick this back up.

Was easier then I thought.

I have questions about issue scoping, this is a super simple and small change, but similar issues have been committed already, setting this to rtbc based on those

Yes it's tempting to ask for a wider scope, but I think we did all the 1-1 (at the time) changes in one go originally and are left with tests that need small modifications in order to use testing profile, so it is probably fine.

Committed/pushed to 11.x and cherry-picked to 10.2.x, thanks!
