I seem to have reached the limits of the Capybara::RackTest driver, as I
have some examples in spec/requests/user_reports_spec.rb that will not
pass because RackTest cannot properly handle 302 redirects.

Because of this, I am trying to move to Capybara::WebKit with a headless
driver. So far it has been unsuccessful, but once I figure it out it
should provide a much more capable testing environment.

I also updated some gems.
