TemplateSettings calls the translate function `tr` because `t` is a
template variable there, and both the key harvester and the coverage
test only looked for `t('...')`. Ten of its keys were never added to
locales/rn/en.json, so they could not be translated and the test did
not notice. Both now also match `tr('...')`, and the missing keys are
added.
