>  Currently {{isEmpty}} API is always return false in {{BaseRepeatedValueVector}}, and its subclass {{ListVector}} did not overwrite this method.
> This will lead to incorrect result, for example, a {{ListVector}} with data [1,2], null, [], [5,6] should get [false, false, true, false] with this API, but now it would return [false, false, false, false].
