chore(cli): tests that apply only to v1 are failing when building for…

… v2 (aws#15565)

In v1 we are allowing selection by the ID of the stack, with a warning that it will be stop working in v2 and asking the user to use the same names shown in the `cdk ls` result. Since the tests are written with the ID as input, they work when building for v1, but fail when building for v2. This change makes it work in both cases.
