> I updated ParquetRecordWriter to delete the last file created if it's empty (no records
written to it). I also added two unit tests one that checks the default case where we try
to create a table using a query that returns 0 rows, the second case can happen if the ParquetRecordWriter
flushes it's content just after writing the last record, it will then create a new empty file.
