translations: prepare project for weblate

As we're changing the translation web service, it's important to be sure
that the dev branch is up to date against the transifex project.

* Removes the test on fuzzy translations, as weblate makes a good use of
  this information.
* Pulls the translations from transifex.
* Extract messages and update catalog.
