Admin route

[strues]

Description

Currently navigating to the default admin route, /admin results in a blank page. Before the migration to React Router 4, multiple index routes were a non-issue.

Exploration into better options on handling route management and layout design needs to be looked into. A blank page is unacceptable. Another possible, yet not as optimal solution would be to render the widgets on the AdminDashboard component. The components would be viewable only on the /admin path and toggled on/off with component state based on the current path
