Should also fail if we get some other exception other than
ColumnNotFoundException -- can have a second catch block for Throwable and then
fail() in it.

(I know this is a copied test, but good to do the simple fixes while
we're at it)

> {code}
> When splittable SYSTEM.CATALOG rollback is enabled, we store the parent's
> column metadata along with the view as well. After the first drop column
> command, metadata for column 'C' of the parent is removed from the view's
> metadata rows however it is not marked diverged, nor is an EXCLUDED_COLUMN
> entry made for that column in the view metadata rows.
> Because of this, when resolving the view we potentially keep combining the
> parent table columns and still get column 'C'. When the second drop column
> command is issued is when we actually add an EXCLUDED_COLUMN linking row for
> 'C' in the view metadata.
