Update singleton usage, fix callback params
The existing usage of OuyaFacade tried to create an instance with the same name. I've changed this usage to simply grab the singleton instance inline for every use case which also eliminates the need for storing an instance of the facade.

The onFailure callback for CancelIgnoringOuyaResponseListener was missing the bundle parameter.  Also there was a log statement that was missing a semicolon.
