…let prune fall through
Query like `select * from ut_p partitions(p2) where cast(var['a'] as int) >
0` will fall through parition/tablet prunning since it's plan like
```
mysql> explain analyzed plan select * from ut_p where id = 3 and
cast(var['a'] as int) = 789;

```
with an extra LogicalProject on top of LogicalOlapScan, so we should handle
such case to prune parition/tablet
