> A test which does a columnPrefixFilter("tag0") AND columnPrefixFilter("tag1") should
return 0 kvs; instead it returns kvs with prefix "tag0".
> {code}
> table = HTable.new(conf, tableName)
> put = Put.new(Bytes.toBytes("row"))
> put.add(cf1name, Bytes.toBytes("tag0"), Bytes.toBytes("value0"))
> put.add(cf1name, Bytes.toBytes("tag1"), Bytes.toBytes("value1"))
> put.add(cf1name, Bytes.toBytes("tag2"), Bytes.toBytes("value2"))
> table.put(put)
> # Test for AND Two Column Prefix Filters
