add relabeled_clone to CTEColumn

[pwfff]

This is probably the worst way to do it, but it works for me. Because the cte.col.column_name has no reference the the cloned query when it's cloned in resolve_expression, I'm just adding this table alias when it happens. It probably won't work if it's nested more than once.

Yeah, this is definitely the wrong approach. I can make it recursive to handle my other failing test cases, but I think the real fix is somehow changing the ._cte reference on the CTEColumn to reference the actual query it's on instead of the original query you used to get the CTEColumn. I'm trying to figure out how to do that now.

Got it 😅
Just needed to add relabeled_clone to CTEColumn.

This looks good, thanks for following up. Do you mind squashing the changes into a single commit on this PR?

[pwfff]

For sure, done.
