Removed incomplete JUnit test that was created by Hans Bakker in commit 1449615 in order to test the feature associated to a new field calcTaxAfterPromotion; after this, Paul Foxworthy reverted the commit in rev. 1468865 but he forgot to remove the whole test and instead he updated it, leaving it in a useless state.
