Error when RoleRepresentation.getDescription() returns no description

[schuerg]

Current Behavior

An error is thrown when org.keycloak.representations.idm.RoleRepresentation.getDescription() returns null.

It happens, when roles have no description.

This happens here https://github.com/adorsys/keycloak-config-cli/blob/main/src/main/java/de/adorsys/keycloak/config/util/KeycloakUtil.java#L50

Cannot invoke "String.equals(Object)" because the return value of "org.keycloak.representations.idm.RoleRepresentation.getDescription()" is null
	at de.adorsys.keycloak.config.util.KeycloakUtil.isDefaultRole(KeycloakUtil.java:50)

Here is the complete error log with stacktrace:
