NetCash.Tests.LotFixture.Can_Scrub_Accounts fails (in GnuCash 5.9)

[gamorris]

Trying to run the unit tests with GnuCash 5.9, I am getting a failure in LotFixture.Can_Scrub_Accounts:

      Message: 
        Assert.True() Failure
        Expected: True
        Actual:   False

      Stack Trace: 
        LotFixture.Can_Scrub_Accounts(TestingBook testingBook) line 6

That assertion appears to be the main one of the test:

  // every lot should be closed
  Assert.True(allLots.Select(x => x.Closed).Aggregate((a, b) => a && b));

Unfortunately I don't really understand "scrubbing" in GnuCash so I can't offer very much here.
