fix: Order of messages if Sentbox is synced before Inbox

[iequidoo]

See commit messages.

My devices go online/offline independently and i use both to send messages, so often i see my messages wrongly ordered around incoming messages.

The test i added here isn't needed, there's test_old_message_5() already which does the same, but instead records the current (wrong) behaviour. Going to fix it then. EDIT: Done

Btw, i think it may be useful to display these outgoing received messages (i.e. from other MUAs/devices) somehow differently e.g. align them to the left as incoming ones. As they still have another brightness (even in Dark mode), it shouldn't be a problem to differ them from incoming messages. May be even useful for shared/community accounts, not sure. CC @adbenitez

Recently i started to see my messages weirdly ordered around incoming ones every day when i open my laptop lid (i.e. i see my replies above incoming messages). I don't know whether Delta Chat started scheduling smth differently or i changed its usage pattern, but this PR should help it seems.

The PR description is quite short, the PR is easier to understand if the PR description has a short explanation in which way the logic was changed.

I'm pretty sure that non-technical users would find this super confusing.

So, this means that this is a breaking change (i.e. will need UI adaptions)? If so, this PR should start with fix! instead of fix, and the PR description should mention this.

And, it means that outgoing messages that were sent by a different device won't have any checkmarks anymore? I personally don't think that's a good idea because that's not how users know it from other messengers, but if others think otherwise, I'd be happy to be outvoted / convinced otherwise.

No, it shouldn't be a breaking change, i forgot to map OutRcvd to OutDelivered in all APIs. Fixed this.

EDIT: Only for REPL the display of received outgoing messages changes.

I put everything to commit messages to avoid updating the PR description every time they change. Probably it's better to leave the PR description empty then or just reference the commit messages.

Probably yes, though for shared/community accounts this may be useful, but then also we need to check for presence of override_sender_name to avoid confusion for other users. Anyway currently in the message Info the user can check if it's a sent or received outgoing message, so my proposal doesn't add smth new, this is only a question of usability.
