cfme_pages salvage

- some of the region tests
- testing the nav fixtures
- testing the phantom login

Modifications:
- Added `_page_title` where needed to some cloud page stubs to get all the fixture tests passing
- Exposed DashboardPage on the header menu to make `intel_dashboard_pg` work
- Added a BZ link and better assertion error message to the phantom login test, also removed the xfail mark (we filed a bug, so we expect it to pass...)
