chore(tests): Remove unnecessary explicit Flask-SQLAlchemy session expunges #27136

Merged

SUMMARY

There's a few instances within our tests where we explicitly expunge either specific or all objects from the session, however this is unnecessary as the Flask-SQLAlchemy session is torn down after each test (verified via logging) in which the current session is removed/closed and thus there's no need to explicitly expunge the records.

Note this change is a precursor to defining a "unit of work" as part of SIP-99B. I've been struggling to get the various unit/integration tests to pass in my PoC—in part due to atypical testing patterns.

It seems weird that we were expunging all objects from the session and not just the chart in question.
