function UserAdminLanguageTest::testUserAdminLanguageConfigurationAvailableIfAdminLanguageNegotiationIsEnabled

Tests that the admin language is configurable only for administrators.

If a user has the permission "access administration pages" or "view the administration theme", they should be able to see the setting to pick the language they want those pages in.

If a user does not have that permission, it would confusing for them to have a setting for pages they cannot access, so they should not be able to set a language for those pages.
