Don't use Bootstrap tabs for our tabbed navigation, as those are meant for single page applications, not for links that reload the page.

use view_name instead of name when getting tab out of the registry

Also refactored some of the tests to pick out the args of interest
sent to render_string

As Dashboard has WidgetInstance objects, TabbedPage has TabInstance
