Eugen Rochko 9b50a9dd83 Fix some ActivityPub JSON bugs (#4796)
- Fix assumption that `url` is always a string. Handle it if it's an
  array of strings, array of objects, object, or string, both for
  accounts and for objects
- `sharedInbox` is actually supposed to be under `endpoints`, handle
  both cases and adjust the serializer
