[bugfix] Status visibility + excludeReplies fixes (#769)

* Fix some bugs when viewing a user's posts: include their self-replies (threads) even when excludeReplies is set, and use in_reply_to_uri instead of in_reply_to_id to filter out replies

* Assign values to InReplyToURI when creating statuses. Add index and update old statuses with a migration
