Class viewer does not save filters when closed

Regardless how the filters are set in the Class Viewer window, closing and reopening the window causes the filters to be reset to the default options.

Regression:
No - this behavior exists in 4.15.3 Binary as well

1. Open UE4 Editor (any project)
2. Navigate to Window->Developer Tools->Class Viewer
3. Click Filters and click Actors Only to deselect it (this will also deselect Placeable Only)
4. Close and reopen the Class Viewer

Result:
Actors Only and Placeable Only are checked

Expected:
The state of the Class Viewer is saved and Actors Only / Placeable Only are not checked
