* [feature] Discover webfinger through host-meta This implements a fallback for discovering the webfinger endpoint in case the /.well-known/webfinger endpoint wasn't properly redirected. Some instances do this because the recommendation used to be to use host-meta for the webfinger redirect in the before times. Closes #1558. * [bug] Ensure we only ever update cache on success * [chore] Move finger tests to their own place This adds a test suite for transport and moves the finger cache tests into there instead of abusing the search test suite. * [chore] cleanup the test a bit more We don't really need a separate function for the oddly located webfinger response as we check the full URL string anyway * Address review comments * [chore] update config example * [chore] access DB only through state in controller
