Review Comment:
@yihua, you are right, it could lead to an empty result, but the problem is
with `prunedPartitionsAndFilteredFileSlices` in `HoodieFileIndex::listFiles`.
Null partition column values lead to `PartitionDirectory`s with null values due
to used `InternalRow.fromSeq(partitionOpt.get.values)`.
I opened a separate related task: HUDI-7952, and will search for proper
fixing.
