token-cli: Fix unexpected behavior when closing a wrapped SOL account with another wrapped SOL account as recipient (#3278)

* Check if recipient is a wrapped account

* Make clippy and fmt happy

* Avoided mutable, more functional clarity

* Add test for closing wrapped sol account

* wrap the default account

* Fix formatting and failing tests
