Concealed state should be checked on feature created signal accepting.

Scenario:
1. Create Extrusion, ExtrusionSketch, Boolean between them, ExtrusionCut, Partition.
2. Save study
3. Open saved study. The ExtrusionCut result is visualized. Call Hide for Partition, ExtrusionCut is in the viewer however there is no such a result in Bodies.
