* Fix regression from #3842

Simplify the query by omitting all direct statuses. Private statuses
are allowed because they are from accounts we are following (so
by definition)

Resolves #3887 (alternative)

* Adjust test

(This patch has been merged as bugfix and reverted, but still valuable as
improvement)

Previously, we've attached IntersectionObserver twice for boosted statuses:
wrapper Status and wrapped Status. but wrapped Status don't need to manage
intersection and visibility by itself, because it's a part of wrapper Status.

* Actually create conversations given explicit URIs

* Try to get the parent toot in before validation, to avoid creating a new conversation

The classes using Status.as_home_timeline, namely Feed and
PrecomputeFeedService are expected to filter direct statuses as
FanOutWriteService does, but their filtering were incomplete or missing.

This commit solves the problem by filtering direct statuses in
as_home_timeline as the other similar methods such as as_public_timeline
does.

* Invalid acct is an error. not "2 errors".

This fixes below bugs:

This fixes a bug that sometimes boosted statuses being hidden on scrolling.

Previously, we've attached IntersectionObserver twice for boosted statuses:
wrapper Status and wrapped Status. This will call intersection handler twice,
so this may results race condition...probably.
