fix: Securejoin: Mark 1:1s as protected regardless of the Config::VerifiedOneOnOneChats

As per the comment in `receive_imf.rs`, `chat.protected` must be maintained regardless of the
`Config::VerifiedOneOnOneChats`. The only thing that mustn't be done if `VerifiedOneOnOneChats` is
unset (i.e. for non-supporting UIs) is marking chats as "protection broken" because this needs
showing the corresponding dialog to a user.
