NetCash.Tests.TransactionFixture.Can_Transfer_Between_Different_Currencies fails (in GnuCash 5.9)

[gamorris]

First off: Thank you for writing this library. It looks like it is going to save me a lot of time with my current project!

Running the test suite, I am getting a failure in TransactionFixture.Can_Transfer_Between_Different_Currencies. My local GnuCash version is 5.9. The failure is:

      Message: 
        Assert.Equal() Failure
        Expected: 15.71
        Actual:   100

      Stack Trace: 
        TransactionFixture.Can_Transfer_Between_Different_Currencies(TestingBook testingBook) line 165

Looking at the test book in GnuCash I see the test transaction created. It has amount $100 in the "Cash in Wallet (USD)" account.

I tried to poke at what the test is trying to do a little bit, but unfortunately I don't understand what is supposed to be happening there well enough to make very much progress on debugging this.
