[Bugfix]修复ConsumerAssignment类型转换错误的问题

Browse Source 
1、问题
KSGroupDescription 的 KSMemberBaseAssignment 对象，转 KSMemberConsumerAssignment 时，会出现转换失败的错误。

2、原因
KSPartialKafkaAdminClient 在返回 KSMemberDescription 时，当 ConsumerGroup 的 memberAssignment.length() <= 0 时，遗漏对 memberBaseAssignment 对象进行初始化。

3、解决
发现 memberAssignment.length() <= 0 时，主动将 KSMemberDescription 中的 memberBaseAssignment 赋值为 KSMemberConsumerAssignment 对象。
