Sui Feature Request - Minor bug with domain display in wallet

[yjshi2015]

Steps to Reproduce Issue

If a nickname is set first in the wallet's account and then a domain name is requested, the domain name is not automatically displayed in the wallet and there is no entry point to view the domain name(If you don't have a nickname set up you won't have this problem).

It can only be done as follows:

1. delete the account and re-import it, but this is a very dangerous operation.

2. Set the nickname to null value in the place of modifying the nickname, because the display priority is Nickname > Domain > Address, but this way may not be too friendly for common users.

   const accountName = account?.nickname ?? domainName ?? formatAddress(account?.address || '');

Expected Result

When modifying nicknames, display the domain name, and users can choose whether to use the domain name or continue to use the nickname. like this:
