Remove 30% coverage threshold from fetch-translations
Remove 30% coverage threshold from fetch-translations

It wasn't an effective rule for weeding out inactive translations - a 20% coverage of wagtailadmin is better than 100% coverage of wagtailsites.
(minimum-perc=1 is required because otherwise it'll pull in languages with no coverage at all, which includes a lot of junk)
