Describe the bug / error

Navigation fails with document sets. Document libraries has documents set content type. Document set content type has default view specified in content type settings. User filters default root folder by specific columns. Then user navigates to inside document set and the view is changed, but these problems appear:

1. Filtering is not cleared. User usually sees empty document set content and has to clear the filter manually each time.
2. If the filtered column is not present in document set default view, the error appears.
3. Custom command bar extension build with SPFX is not present when you are inside document set. Have to refresh the window.

Steps to reproduce

1. Add Document set content type to document library.
2. Add Column A - to document library and ensure it is added to all content types and views.
3. Ensure "Column A" is added to default view
4. Create new view "Contents" - remove "Column A" from that view.
5. Set "Content" as default view for Document set content type.
6. Create one document set, fill "Columns A", with value "TEST",
7. Add one document inside document set.
8. Go to root folder of the library, filter view by column "Column A" with value TEST.
9. Go inside first document set.
10. Observe opened view.

Expected behavior

View should switch to view "Contents" - OK.
Document should be visible inside document set - FAIL.
Filters should be cleared inside document set - FAIL.
When navigate back to root folder - view should be switched back to lists default view - FAIL.
