fix: stop sending clientId to avoid E00013 errors

The SDK injected an undocumented `clientId` (`sdk-java-<version>`) onto every request via the
controller constructor. The Authorize.Net API now rejects requests containing this field with
`E00013 "The field is invalid."`

Removing the `setClientId()` call leaves the field null so JAXB omits it from the serialized
request. Mirrors the sdk-php fix in AuthorizeNet/sdk-php#475 (fixes AuthorizeNet/sdk-php#474).
