Remove the dashboard. Fix test app generation.

One javascript test is still failing, but I can't figure it out:
```
1) end to end behavior help request with JS is available for users who are authenticated and agreed to ToS
     Failure/Error: click_link "Request Help"
     Capybara::ElementNotFound:
       Unable to find link "Request Help"
     # ./spec/features/end_to_end_spec.rb:172:in `block (3 levels) in <top (required)>'
```

This may have been failing prior to this since js tests are not run on CI.
