Bump test-unit and mocha

test-unit and mocha and rails has compatible problems. Use latest version
Require active_support/testing/autorun if if ActiveSupport::VERSION::MAJOR > 3

Otherwise rake test does nothing :(
Use :via option to suppress an error

normalize_conditions!: You should not use the `match` method in your router without specifying an HTTP method. (RuntimeError)
Fix test, use :controller option instead of :to

With rails4, this test did not pass.
  VerificationTest#test_no_deprecation_warning_for_named_route:
  ActionController::UrlGenerationError: No route matches {:two=>"not one", :controller=>"verification_test", :action=>"guarded_one_for_named_route_test"}

I thought :controller option is same meaning.
Add .travis.yml to test multiple rails environment
