[GNC] Reconcile w/ open transaction

[Fred Tydeman]

I updated three transactions by changing N to C in the R column and
correcting the amount in the last of the three transactions.
I did a Reconcile and ended it with Finish.
I tried to save the book / file.  That got me a popup telling me I had an
open transaction and should I close it.  I clicked on: close it.
The Y from the Reconcile reverted back to the C before the Reconcile.
So, I had to do the Reconcile again.
It seems to me that trying to do a Reconcile should check for any open
(not saved) transactions before starting the reconcile process.
