Fixed the bug regarding EliminateEmptyNode and InsertSelection.
This PR fixed a bug regarding `EliminateEmptyNode` and `InsertSelection`
that could be easily reproduced as the following:
```
CREATE TABLE temp (a int);
\analyze
INSERT INTO temp SELECT i FROM generate_series(1, 100) AS gs(i);
```
The problem is that `InsertSelection` allows the destination table to be
empty, but the rule does not catch that.
