Review Comment:
We need to be able to restore a `CaseExpr` in
`CaseExpr::with_new_children()` from the a `children: Vec<Arc<dyn
PhysicalExpr>>`. If we don't push anyting for the 2 optional `CaseExpr.expr`
and `CaseExpr.else_expr` fields, then I don't think there is a way to tell if
the first element of `children` belongs to the optional `CaseExpr.expr` or to
`CaseExpr.when_then_expr`.
