0027523: Visualization - selection owner contains obsolete shape

- remove check for selection activation in SelectMgr_SelectionManager::RecomputeSelection;
- given selection mode is now handled properly and single selection mode can be recomputed;
- test case for issue #27523.

Small correction of test case for issue CR27523
