0027893: Visualization - AIS_InteractiveContext::SetSelected does not work

- misprint in check of global selection existence in AIS_InteractiveContext::SetSelected was corrected;
- remaining occurrencies of hard-coded 0 selection mode were corrected to use global selection mode;
- test case for issue #27983
