ThibG 0d5f3ae331 Fix already-known remote private toots not being searchable by URL (#12336)
* Fix already-known remote private toots not being searchable by URL

Whenever an URL search fails, and an account is provided, try getting a
private status matching that URL from database.

* Fix searching by `id` field instead of `uri`
