RedisWatcherAutoConfigration bug

[ShingmoYeung]

in

src/main/java/org/casbin/spring/boot/autoconfigure/CasbinRedisWatcherAutoConfiguration.java

casbinProperties.getPolicyTopic() should be passed in, not redisProperties.getClientName().

// fixed channel-name RedisWatcher watcher = new RedisWatcher(redisProperties.getHost(), redisProperties.getPort(), casbinProperties.getPolicyTopic(), timeout, redisProperties.getPassword());
