RestOauthControlles does not trigger RestTokenCreationEvent

[jjchiw]

Is there a reason why the RestTokenCreationEvent is not triggered when a new Token is generated using the refreshtoken is in this method (https://github.com/alvarosanchez/grails-spring-security-rest/blob/84cf34181bffdeace476b6f963ba18af51ac84a8/spring-security-rest/grails-app/controllers/grails/plugin/springsecurity/rest/RestOauthController.groovy#L119)

The docs state that the the RestTokenCreationEvent that everytime that a new token is created the event is triggered

6.1.2. Token Creation

Currently the Spring Security REST plugin supports a single event in addition to the default spring security events. The event is fired whenever a new token is created.

Thanks for the great plugin
