I made a fix for broken array and map in `JsonToStructs` because inside of
`FailureSafeParser` is not clear from where the call came. I am still not sure
that wrapping actual type by `StructType` before passing it to
`FailureSafeParser` was right decision in #22237 /cc @cloud-fan Doing this we
cannot distinguish `ArrayType`/`MapType` as root type from
`StructType(StructField(ArrayType/MapType))`, and return appropriate null
result in the case of bad record.
