ReportGuiManager printReport(report, params) throws NPE #158

Environment

CUBA version: 7.0.1

Description of the bug or enhancement

ReportGuiManager has an API to print and download a report with parameters.

See: https://github.com/cuba-platform/reports/blob/master/modules/gui/src/com/haulmont/reports/gui/ReportGuiManager.java#L175

This API variant is broken in 7.0.1. When executing it a NullPointerException is thrown in UiControllerUtils. It seems there is a screen needed, but the API variant defines null as the screen (see: https://github.com/cuba-platform/reports/blob/master/modules/gui/src/com/haulmont/reports/gui/ReportGuiManager.java#L176).

Minimal reproducible example

Example

cuba-problem-report-npe.zip

Note: Report has to be imported before. Report is located in reports sub directory.

Expected behavior Either the Report should be generated or it should not be possible to run this API variant without passing in a screen
Actual behavior NPE is thrown
