Fix - TestSchedulerJobQueriesCount::test_process_dags_queries_count

[mik-laj]

The first time this test was broken in the following commit.
406ed29 Make Dag Serialization a hard requirement (#11335)
And the number of database queries has changed: Fortunately, it was optimization.
92e405e Call scheduler "book-keeping" operations less frequently. (#12139)

A few more tests look like they might be broken too:

airflow/tests/jobs/test_scheduler_job.py

Line 1742 in 92e405e

with mock.patch.object(settings, "STORE_SERIALIZED_DAGS", True):

airflow/tests/jobs/test_scheduler_job.py

Line 3712 in 92e405e

settings, 'STORE_SERIALIZED_DAGS', True

Thanks to @potiuk for creating the quarantine test list. This allowed me to see that the tests that had previously been only partially unstable. Now it was never successful.

@kaxil I am afraid that this test may not start for some reason. I tested locally and I have a message that this attribute is missing. It have been deleted. See: https://github.com/apache/airflow/pull/11335/files#diff-230a06cebe53507c57e3076e4651050de7b8e741212f304acc516a338fce3332L347-L349

Got it, yes, right

[kaxil]

I will fix the other tests where config is still there

The PR needs to run all tests because it modifies core of Airflow! Please rebase it to latest master or ask committer to re-run it!

I checked the log for those tests on CI and these tests are now green.
