Samsung device doesn't seem to call `onAuthenticationError` and `onAuthenticationFailed`

[schreiby]

Hi,
This library works great on my Nexus 5X and works just like Android's fingerprint API says it should.

I'm just wondering about Samsung. I'm running a Galaxy S8+ with Android 9. A registered fingerprint authenticates successfully, but if it doesn't scanFail() doesn't seem to trigger and the dialog doesn't dispose.

Any ideas?

Thanks!
