> 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].
