ForceMentionsInContent: fix double mentions for Mastodon/Misskey posts

The code checked for duplicates using "ap_id", but in Mastodon and Misskey the look like that:
Mastodon: https://mastodon.example.com/users/roger
Misskey: https:///misskey.example.com/users/104ab42f11

The fix is to also check for "uri", which is what will be in the "explicitly_mentioned_uris" list:
Mastodon: https://mastodon.example.com/@roger
Misskey: https://misskey.example.com/@roger
