iequidoo 6d8dff54a7 fix: Ignore protected headers in outer message part (#6357) ...

Delta Chat always adds protected headers to the inner encrypted or signed message, so if a protected
header is only present in the outer part, it should be ignored because it's probably added by the
server or somebody else. The exceptions are Subject and List-ID because there are known cases when
they are only present in the outer message part.

Also treat any Chat-* headers as protected. This fixes e.g. a case when the server injects a
"Chat-Version" IMF header tricking Delta Chat into thinking that it's a chat message.

Also handle "Auto-Submitted" and "Autocrypt-Setup-Message" as protected headers on the receiver
side, this was apparently forgotten.
