Attempting to re-register an account that has already been registered causes an error.

[johnnymatthews]

This is fairly obvious, but if you attempt to register an account that has previously been registered, you get an error, and are kicked out of the CLI:

2024-07-18 14:46:21        REGISTRY: Unknown signed extensions ValidateConfirmRegistered found, treating them as no-effect

Tasks

• Catch the error before the user is thrown out of the CLI.
• Tell the user that you can't register an account more than once.
