Add a test for checking that all languages have autonyms

DRAFT
Some languages don't yet have autonyms, but probably all languages should
have them. It currently fails, because there are many such languages and
I am not aware of a nice way to skip it in QUnit (there is a proper skipping
mechanism in Perl testing, for example).

Also change orphanScripts() to return all scripts without groups.
