feat: Don't send SystemMessage::Member* in unencrypted groups

Unencrypted groups are usually ones with other MUAs which don't understand Delta Chat system messages and show them as weird emails. Self-removal returns an error now, otherwise remaining members won't know about it. It should be disabled in UIs and the user should resolve it on their own (e.g. by asking other members).

-//! ```
-//!
-//! or, if you want to only run e.g. the 'Decrypt a symmetrically encrypted message' benchmark:

-//! ```text
-//! cargo bench --bench decrypting --features="internals" -- 'Decrypt a symmetrically encrypted message'

-//! ```text
-//! cargo bench --bench decrypting --features="internals" -- 'Decrypt and parse'

-//!
-//! Symmetric decryption has to try out all known secrets,
