Fix a bug reported by Rong Nguyen "Tracking code report in Marketing doesn't work" https://issues.apache.org/jira/browse/OFBIZ-5556

I did not use Rong's proposed patch
The problem was simple and due to an error I made in r703816. 
I then replaced
-if (trackingCodeIdStr && !(trackingCodeIdStr.equals(""))) {
by
+if (trackingCodeIdSt) {
which was wrong
Then trying to fix an error reported somewhere (not mentioned) Hans went in a wrong direction with r761539+761541

So I reverted r761539+761541 and fixed the issue above in a clean way by setting the field in the calling screen. This way there are no possible issues with i10n and NPEs.
