Make all autonyms unique and add a test for this

In a list of languages to select autonyms must be unique so that
every user would know what to select.

* Batak Toba language in the Batak writing variant (bbc-batk) has
  an autonum in the right script now. This is taken from the Indonesian
  Wikipedia article "Surat Batak".
* Similarly to the practice with pa -> pa-guru:
  * iu for Inuktitut in the Canadian script redirects to ike-cans.
  * ks for Kashmiri in the Arabic writing redirects to ks-arab.
  * tg for Tajik in the Cyrillic script redirects to tg-cyrl.
* zgh has an updated autonym, taken from Ethologue.
* zh-classical redirects to lzh, similarly to zh-yue -> yue.
