Fix select on empty lists (#8651)
This PR fixes `select` when given an empty list; it used to return
`null` when given an empty list. I also cleaned up other `select` tests
while I was in the area.

### Before:

```
> [] | select a | to nuon
null
```

### After:

```
> [] | select a | to nuon
[]
```

It looks like the previous behaviour was accidentally introduced by
[this PR](https://github.com/nushell/nushell/pull/7639).
