import-translations: work around the lack of usable branches in Tor's translation.git (refs: #17279) For all our Transifex resources but tails-misc, Tor's translation.git currently has no usable branch: - The _completed branches that we pull from only have languages which are fully translated and reviewed, i.e. very few translations. - The non-_completed branches have have non-reviewed translations, which we don't want to ship anymore. The real fix will be https://redmine.tails.boum.org/code/issues/16774#note-25. We've been waiting for it for 3 months now, and it's not sustainable that the RM has to manually workaround the currently problematic situation by hand during every release process. So in the meantime, keep shipping the PO files we've already imported when no suitable up-to-date one is available.
