Improve group updates

- Check that member modifying the group is in the group themselves.

  It is not allowed to readd yourself to the group or remove someone without being in the group themselves.

- Unify code for group member addition and removal.

  Removing a member now recreates the group member list from the To: field.

  Removed member from the Chat-Group-Member-Removed was in the To: field in previous Delta Chat versions,
  so it is excluded explicity. New versions of Delta Chat put removed member in Bcc: instead.

- Apply avatar changes after updating the group member list.

  This allows to check that the contact modifying the avatar is actually a group member.
