SERVER-77172  introduced a new code path that can terminate the session without logging this line.

this situation can occur when the abortExpiredTransactions job takes longer than the gAbortExpiredTransactionsSessionCheckoutTimeout, which is set to 100 milliseconds, after the multi-statement transaction's OperationContext has been killed to check out its session.

So for this test we need to set AbortExpiredTransactionsSessionCheckoutTimeout to a large value to not fail on slow machine.
