[HOTFIX] [CORE] fix flaky BasicSchedulerIntegrationTest
## What changes were proposed in this pull request?
SPARK-15927 exacerbated a race in BasicSchedulerIntegrationTest, so it went
from very unlikely to fairly frequent. The issue is that stage numbering is
not completely deterministic, but these tests treated it like it was. So turn
off the tests.
## How was this patch tested?
on my laptop the test failed abotu 10% of the time before this change, and
didn't fail in 500 runs after the change.
