Scope to company when viewing assets (#2315)

* If a user doesn't belong to a company, when scoping to a company we should only show items that don't belong to a company.

* Scope tables/items to the company they belong to when fetching items for the index.

* Fix asset count to also scope to company.  This fixes dashboard view

* Exempt super users from the child company check to be consistent.  Fixes license count on dashboard now that we scope everything
