Redundant assertion in `RedisTemplate.afterPropertiesSet(…)`

[foaw]

In RedisTemplate#afterPropertiesSet, if any of serializers are null and enableDefaultSerializer is true, they are set to defaultSerializer. After this, it checks if the defaultSerializer was also null, in which case an exception should be thrown. However, this cannot be the case, as defaultSerializer is pre-initialized to JdkSerializationRedisSerializer, if null.

	defaultSerializer = new JdkSerializationRedisSerializer(
	classLoader != null ? classLoader : this.getClass().getClassLoader());
	}

	Assert.notNull(defaultSerializer, "default serializer null and not all serializers initialized");
	}

Thank you @foaw for raising the issue. We'll have a look.
