Actually we do handle stars in `CreateArray` and `CreateStruct`:
https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L440-L458,
so what you are fixing is the nested `CreateStruct`, I think we should also
add `CreateArray` too.
One of my concern is: sometimes we check stars under `UnresolvedAlias` but
sometimes also under `Alias`, it will be good if you can figure it out and make
sure there is no missing case.
