The return value is never used here; later stages which actually need it
fetch the user themselves and it doesn't matter wheter we wait for the
fech here or later (if needed at all).
Even more, this early fetch always fails if the user was already deleted
or never known to begin with, but we get something referencing it; e.g.
the very Delete action carrying out the user deletion.
This prevents processing of the Delete, but before that it will be
reattempted several times, each time attempring to fetch the
non-existing profile, wasting resources.
It was used to migrate OStatus connections to ActivityPub if possible,
but support for OStatus was long since dropped, all new actors always AP
and if anything wasn't migrated before, their instance is already marked
as unreachable anyway.
The associated logic was also buggy in several ways and deleted users
got set to ap_enabled=false also causing some issues.
This patch is a pretty direct port of the original Pleroma MR;
follow-up commits will further fix and clean up remaining issues.
Changes made (other than trivial merge conflict resolutions):
- converted CHANGELOG format
- adapted migration id for Akkoma’s timeline
- removed ap_enabled from additional tests
Ported-from: https://git.pleroma.social/pleroma/pleroma/-/merge_requests/3880
Otherwise attachments have a high chance to disappear with akkoma-fe’s
“delete & redraft” feature when cleanup is enabled in the backend. Since
we don't know whether a deletion was intended to be part of a redraft
process or even if whether the redraft was abandoned we still have to
delete attachments eventually.
A thirty minute delay should provide sufficient time for redrafting.

Current logic unconditionally adds public adressing to "cc"
and follower adressing to "to" after attempting to strip it
from the other one. This creates serious problems:
First the bug prompting this investigation and fix,
unconditional addition creates duplicates when adressing
URIs already were in their intended final field; e.g.
this is prominently the case for all "unlisted" posts.
Since List.delete only removes the first occurence,
this then broke follower-adress stripping later on
making the policy ineffective.
It’s also just not safe in general wrt to non-public adressing:
e.g. pre-existing duplicates didn’t get fully stripped,
bespoke adressing modes with only one of public addressing
or follower addressing are mangled — and most importantly:
any belatedly received DM or follower-only post
also got public adressing added!
Shockingly this last point was actually asserted as "correct" in tests;
it appears to be a mistake from mindless match adjustments
while fixing crashes on nil adressing in
10c792110e.
Clean up this sloppy logic up, making sure no more duplicates are
added by us, all instances of relevant adresses are purged and only
readded when they actually existed to begin with.
