manage libraries: context-menu activate/deactivate selected shows no immediate effect

Description

The "Manage symbol libraries" / "Manage footprint libraries" dialogs possess a context-menu with commands to bulk-activate / bulk-deactivate selected libraries. Using these commands has no immediate effect on the visual display of the "active"-checkboxes for the selected libraries, the dispayed checkbox-state remains unchanged.

Only after a window-refresh (changing to a different program, or clicking somewhere in the dialog) the new checkbox-state is displayed.

affects:

• v7.0 and v7.99
• manage symbol libraries dialog
• manage footprint libraries dialog

Steps to reproduce

1. open kicad, goto kicad-manager
2. open Preferences-->manage libraries
3. select some libraries, preferred un-activated (see picture 1)
4. RMB-click-->context-menu --> activate selected (see picture 2)
5. after click on "activate selected": context-menu is cleared, libraries remain selected, but active-checkboxes on the left remain unchanged (see picture 3)
6. with Windows system-wide hotkey "Alt+Tab" switch to a different program and back --> only now the active-checkboxes are shown with the new "active" state (see picture 4)
