* refactor: cleanup send_handshake_msg() - rename to send_alice_handshake_msg() as used by Alice only - remove dead code from Bob (Bob's code is at BobState::send_handshake_message() since some time) - take a contact_id and not a chat_id; this makes things less confusing when info-messages are put to the final group chat * always directly return chat-id from dc_join_securejoin() * take care not to create a group twice * adapt documentation * add info-msg on group invites; add inviter directly after creation * document existing 'joinqr' command in repl tool * do not create empty one-to-one chats for group-joins * refactor: cleanup fingerprint_equals_sender() - the function takes a contact_id directly now. before it consumes the first contact of a one-to-one chat - which may be easily confused with the group-chat in creation. moreover, the conversion contact_id -> chat_id -> contact_id is unneeded overhead. * show info-messages in destination chat for alice * fingerprint_equals_sender() returns Err on database failure * tweak documentation * clarify what an 'unfinished tasks' task is. * add regression test for create_for_contact_with_blocked() * rename Blocked::Manually to better fitting Blocked::Yes * tweak test_secure_join() and make sure, Alice and Bob have only on chat after a group-join
