Subject: [PATCH] Fix followers synchronization mechanism not being triggered
 on mentions (#15026)

e.g. if someone on an instance that previously had followers gets mentioned
in a private toot, before this PR, they would not receive a
Collection-Synchronization header and may show the toot to the former followers
in addition to the mentioned person.
