fix(history): save name to history for friend invite message

This avoids an extra alias table entry for the empty name. It is not possible to safely heal existing databases, since friend invite message is a normal action message making it hard to change the alias ID used by it, and the alias in the alias table could be used by any other messages if the user's name has ever truely been blank. Just avoid the incorrect alias entry for new chats.
