Fix failing model contract integration test (#378)

* Fix failing model contract integration test

TestInvalidModelContractCheckConstraints tests that an invalid constraint causes a failure.  The test checked that the error message contained 'Constraint validation failed'.

dbt 1.5.2 changed the error message to 'Contract enforcement failed'.

Updated the test to check for either the original or updated message.
