fix compact to handle empty list or record in column (#15213)

If a table contains an empty list or record in one column and both column
and -e flags are used, then skip that row.

`compact -e` now skips empty values in a column where as before they were
ignored. Example:

 ```nu
[["a", "b"]; ["c", "d"], ["h", []]] 
| compact -e b
```
before

```plain
 #   a         b
────────────────────────
 0   c   d
 1   h   [list 0 items]
```
after
```plain
 #   a   b
───────────
 0   c   d
```
