NPE in Java_org_rocksdb_ColumnFamilyOptions_setSstPartitionerFactory (#9622)

Browse Source 
Summary:
There was a mistake that incorrectly cast SstPartitionerFactory (missed shared pointer). It worked for database (correct cast), but not for family. Trying to set it in family has caused Access violation.

I have also added test and improved it. Older version was passing even without sst partitioner which is weird, because on Level1 we had two SST files with same key "aaaa1". I was not sure if it is a new feature and changed it to overlaping keys "aaaa0" - "aaaa2" overlaps "aaaa1".
