Fix IFingerprint VTS 

The main function was not defined/visible because it was inside of a
namespace. The default GTest main was used instead, and the Binder
threadpool was never initialized, causing the test to hang.

In addition to that, the test expected a single onStateChanged with
SessionState::AUTHENTICATING. Added support and expectations for
multiple callback invocations.
