https://github.com/chatmail/core/issues/8329
This fixes the following bug:
Scanning QR for existing contact doesn't update relay list
Two chat partners suddenly lost connectivity to all of their relays. They added another relay, which is accessible, and set it as main. Of course, they still couldn't communicate, because there was no way to announce a new relay list to each other (clients know only about old relays so they try to send updates there).
That's why the friends used a different channel (e.g. met IRL) to send their QR codes once again.
Expected behavior: They would expect that clients update their relay lists according to the contact info inside the QR codes, and they can continue talking in Delta.
Actual behavior: But Delta Chat client doesn't update a list of announced relays on scanning a QR in case a contact already exists. It simply opens the existing chat without altering any contact info.

Citing @link2xt:

Also this unescapes commas in all fields. This can lead to, say, an email address with commas, but
anyway the caller should check parsed `VcardContact`'s fields for correctness.
About the first TODO: I tried this out, but it didn't actually improve
things, for two reasons:
1. The trick with `#![cfg_attr(not(test),
warn(clippy::indexing_slicing))]` that enables the lint everywhere
except for tests doesn't work with workspace-wide lints. (Context: We
want to lint against indexing because it might panic, but in a test
panicking is fine, so we don't want to enable the lint in tests).
2. Most of our crates have different sets of lints right now, so it
would only be very few crates that use the workspace-wide list of lints.
About the second TODO:
It's not feasible right now to fully parse vCards, and for our
good-enough parser the current behavior is fine, I think. If we fail to
parse some realworld vCards because of this, we can still improve it.
It's actually `deltachat::contact::Contact::authname` by semantics. `display_name`/`name` shouldn't
be shared, it's the name given by the user locally.
Add a function parsing a vCard file at the given path.
