Subject: [PATCH] Do not break gui when fallback language is not available in
 termsdialog.js

L10 falls back to language code, that means if "pt_x" is not available
it falls back to "pt", but we do not provide "pt", same for "en" or
after uninstalling and removing language pack and leaving language
selected.
Adding warning.
