Make new tests tsql compat

[dataders]

necessary updates per #30. It seems there's some fast-moving goal posts for getting dbt-date integration tests passing for the dbt-msft adapters.

I'm struggling to work with the new nested CTEs and ephemeral model that was introduced in the PR.

Double struggle because I thought that this change would at least disable these new models from being run and tested.

models:
  dbt_date_integration_tests:
    dates: &disabled
        +enabled: false
    dim_week: *disabled
    dim_hour: *disabled

@clausherther maybe we can mind meld next week on how to untangle the CTEs? My changes were of no use.

in the meantime, i'm going to disable dbt-date testing from tsql-utils' CI for the time being so I can finally get dbt-msft/tsql-utils#45 merged (and start saving some money by not having Synapse run 24/7)

Ah, sorry, I didn't realize TSQL doesn't support ephemeral models and nested CTEs. I'll keep that in mind! Since I can't test on SQL Server, these sort of things can easily slip by unfortunately.

Happy to get on a quick chat this week, feel free to reach out on dbt Slack.
