update test__model_contract_true

resolves #N/A

Problem

Seeing surprising failures in dbt-core locally after a dbt-common merge to main I just did.

Solution

The dbt-common change itself should be back-compat and so this should be a matter of updating tests. common merge queue did not catch it because of dbt-labs/dbt-common#104
