Mastodon API: Align favoriting / repeating behavior with Mastodon

See merge request pleroma/pleroma!2119

CHANGELOG.md

@@ -44,6 +44,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Mastodon API, streaming: Add `pleroma.direct_conversation_id` to the `conversation` stream event payload.
 - Admin API: Render whole status in grouped reports
 - Mastodon API: User timelines will now respect blocks, unless you are getting the user timeline of somebody you blocked (which would be empty otherwise).
+- Mastodon API: Favoriting / Repeating a post multiple times will now return the identical response every time. Before, executing that action twice would return an error ("already favorited") on the second try.
