Tested with Flaky Tester and failed 3/100 runs on Python 3.8/windows

The test fails in the middle. This happens when run as part of the suite or when run by itself.

In the test run that I looked at the sequence of events is:

• create view ...model_one_downstream__dbt_tmp
• rename model_one_downstream to model_one_downstream__dbt_backup
• fails with "model_one_downstream" does not exist

Looks like this is flaking again: https://github.com/dbt-labs/dbt-core/actions/runs/8341943731/job/22829077630?pr=9769
