Fix test `unsupported Spark types` in ParquetReadSuite

### Describe the bug

This is a regression after merging https://github.com/apache/datafusion-comet/pull/2176

If I set the scan impl to native_iceberg_compat, native_datafusion, or native_comet, then it passes. It just does not work with auto.
