Describe the bug

When using only OmniAuth to access the platform, there is an edge case when user is being redirected to authorizations page, even though the organization does not have any authorizations available.

To Reproduce

1. Go to a Decidim inststance in the system panel
2. Make sure you do not have any authorizations enabled.
3. Make sure you have oimniauth
4. Try to login using a new Omniauth account
5. On the omniauth provider screen, create a new account ( so that u receive the verification link from Service provider )
6. Open the verification link in a new private window ( to simulate outlook or other desktop email client )
7. See that you are being redirected on Oauth provider pages, then TOS, then Authorizations screen.

Expected behavior

Given that i do not have any authorizations, i should not be redirected to authorizations
