fix: filter Break objects and update expected language menu items

Filter out Break objects when checking language menu items since they
don't have a name attribute. Also update the expected result when
versioning is enabled to include 'Add Translation' which is now part
of the menu with the new django-fsm-2 and versioning integration.
