There is a list of languages to update in tests/settings.py + one test

[derzinn]

"Filter" comes already from the Django admin catalog. In all other language files, this ID is flagged as fuzzy because it changes from "List Filter" to "Filter" and will be ignored by compilemessages.

@merwok What do you recommend?

I realized that after and deleted my comment!
I forgot to add the translators note when I copied some templates from django.

These msgids should be fixed (remove the fuzzy marker and incorrect suggestion)!
