Two sessions tests are failing on the unified test runner (but were not for the legacy session test runner).  There is also a duplicate of one of the failing tests in the sessions-poc tests for the unified runner.

Failing sessions tests

• Dirty explicit session is discarded (insert)
• Dirty explicit session is discarded (findAndModify)

Failing session POC test

• Dirty explicit session is discarded

Note: rust and swift drivers both run and pass this test
