ReportGuiManager bulkPrintSync throws NPE

Minimal reproducible example Create report with single entity parameter, add it to entity browse screen (i think legacy browse screen). Add run report action:
```
@Override
public void init(Map<String, Object> params) {
    super.init(params);
    printBtn.setAction(new BaseAction("")
            .withHandler(e -> {
//set report id
                Report report = dataManager.load(Report.class).id(UUID.fromString("ab78f665-8196-a1a4-5733-a326be1495fc")).one();

                reportGuiManager.bulkPrint(report, "entity", personsTable.getSelected());
            }));
}
```
Open browse screen, select few rows and run report - NPE occured. java.lang.NullPointerException at com.haulmont.cuba.gui.screen.UiControllerUtils.getHostScreen(UiControllerUtils.java:190) at com.haulmont.cuba.gui.screen.UiControllerUtils.getScreen(UiControllerUtils.java:199) at com.haulmont.reports.gui.ReportGuiManager.bulkPrintSync(ReportGuiManager.java:603) at com.haulmont.reports.gui.ReportGuiManager.bulkPrintSync(ReportGuiManager.java:574) at com.haulmont.reports.gui.ReportGuiManager.bulkPrintSync(ReportGuiManager.java:622) at com.haulmont.reports.gui.ReportGuiManager.bulkPrint(ReportGuiManager.java:558) I think is some analog of #158
Expected behavior Report with single entity param in case when few rows are selected run successfully (output result is zip archive with few report results for each selected row) It works on 5.9 version
Actual behavior NPE
