Describe the bug

Hi,an exception InvalidDirectVerificationRoute.new may occur in Decidim::Verifications::Adapter.
https://github.com/decidim/decidim/blob/develop/decidim-verifications/lib/decidim/verifications/adapter.rb

But InvalidDirectVerificationRoute seems to be not defined in Decidim. Instead, there was a InvalidVerificationRoute in the file.
Which class is correct?
