Add tests for Cc, AddCc, AddCcFormat, CcIgnoreInvalid, and CcFromString
This commit introduces comprehensive tests for various "Cc" related methods in the `Msg` struct. It includes test cases for valid and invalid email addresses for methods: `Cc`, `AddCc`, `AddCcFormat`, `CcIgnoreInvalid`, and `CcFromString`, ensuring robust handling of different scenarios and edge cases.
