iequidoo 374a5ef687 feat: Don't apply chat name and avatar changes from non-members ...

Non-members can't modify the member list (incl. adding themselves), modify an ephemeral timer, so
they shouldn't be able to change the group name or avatar, just for consistency. Even if messages
are reordered and a group name change from a new member arrives before its addition, the new group
name will be applied on a receipt of the next message following the addition message because
Chat-Group-Name-Timestamp increases. While Delta Chat groups aimed for chatting with trusted
contacts, accepting group changes from everyone knowing Chat-Group-Id means that if any of the past
members have the key compromised, the group should be recreated which looks impractical.
