account moves different to reconcilation moves

[Thorsten Vocks (OpenBig.org)]

This bug is a regression. The calculated cash discount and tax correction is OK in reconcilation fields dialogue for the
following use case.

Invoice amount (with 19% tax) = 11.90 => 10.00 + 1.90 (19%)
cash discount 2%

The lines in reconcilation field for discount and tax correction are:

cash discount 0.20
tax correction 0.04
---------
payment amount 11.66

The bug (regression) follows on tab real entries. The account move is

bank account 11.62 (debit)
cash discount 0.24 (debit) => This should be 0.20 (in hundred calculation!!)
tax correction 0.04 (debit)
vs. debitor / receivabl. acc. 11.90

Reconcilation and real entries doesn't fit. The account moves should be:

bank account 11.66 (debit)
cash discount 0.20 (debit)
tax correction 0.04 (debit)
vs. debitor / receivabl. acc. 11.90

Also in this case the fiscal position mapping was not correct.
