  Changed paths:
    M model/report-impl/src/main/java/com/evolveum/midpoint/report/impl/controller/CollectionExportController.java
    M model/report-impl/src/test/resources/reports/report-indirect-assignments.xml

  Log Message:
  -----------
  CollectionExportController: fixed second evaluation of asRow subreport..

..which happens when asRow subreports generate no rows.
In such case the asRow-subreport variables are provided as empty lists.
Returning null would break some existing reports.
report-indirect-assignments.xml null-safety fixes (probably overstrict)
