TrustedDeviceCondition does not work without configuration

[galimru]

First of all, let me say you did a great work, thank you for that extension!

I think I found a small bug for condition TrustedDeviceCondition when it's added without setting up alias and configuration.
Despite UI shows Negate toggle is enabled by default, the whole configuration is null.
So without it, condition returns always false which skips whole 2FA subflow.

keycloak-spi-trusted-device/spi/src/main/java/nl/wouterh/keycloak/trusteddevice/authenticator/TrustedDeviceCondition.java

Lines 27 to 34 in 05cb4d8

	if (authConfig != null && authConfig.getConfig() != null) {
	boolean negateOutput = Boolean.parseBoolean(
	authConfig.getConfig().get(TrustedDeviceConditionFactory.CONF_NEGATE));
	return negateOutput != trustedDevice;
	}
	return false;

In fact, I don't understand what is purpose of this toggle.

I can corroborate this. Without setting up the Alias even though it is set as default it will not flag the condition as being met.

We can confirm this issue too
