Bug in export tx history

[jl2012]

In exported tx history (csv), there are 2 bugs for records of "loop transactions" (tx within the same wallet):

1. tx fee is not shown
2. The value is shown as "Total Credit", while nothing is shown in "Total Debit"

As a result, the values do not add up correctly

Thanks for the bug report.  I will document this in our bug database and start investigating it.
