For parity with Commerce Accounts, Portal Accounts should support the concept of a "guest account group". The guest account group is used for guest users. B2B solutions can use the guest account group to provide a tailored experience for unregistered users.

Requirements

1. There is always exactly one guest account group.
2. The guest account group name is: "Guest"
3. The guest account group description is: "This account group is used for guest users."
4. The guest account group cannot be edited nor deleted. (no action menu items available).
5. In the table view, the "Accounts" column (the count of accounts) shows "" (StringPool.DOUBLE_DASH).
6. NEW Hide "Guest" account group from list
