Review Comment:
Unfortunately, this is also a valid test and so it shouldn't be altered.
I don't want to block this fix so if we need it urgently I'm ok with mergint
this PR but probably we can come up with a better alternative.
I think the issue is that we try merging a new plan that contains a
`ScalarSubqueryReference` that references a cached plan with the same cached
plan.
