The user canceled message is different than the other fingerprint errors
since it is caused by the user explicitly tapping on the UI at which
point the dialog will be already dismissing/dismissed. So the error
should be sent immediately to the application.
Test: manual test with FingerprintDialog, modified to show when the
error messages are received
