## What changes were proposed in this pull request? In NestedColumnAliasing rule, we create aliases for nested field access in project list. We considered that top level parent field and nested fields under it were both accessed. In the case, we don't create the aliases because they are redundant. There is another case, where a nested parent field and nested fields under it were both accessed, which we don't consider now. We don't need to create aliases in this case too. ## How was this patch tested? Added test. Closes #24525 from viirya/SPARK-27633.
