#648 implements a workaround for the OIDC `returnToUrl` in the case of WebID-TLS, pending a fix for solid/oidc-auth-manager#17. Once solid/oidc-auth-manager#17 is closed, we should: - [x] verify that passing `returnToUrl` to oidc-auth-manager works well - [x] verify that oidc-auth-manager redirects to `returnToUrl` (preserving the hash #562 ) in the case of username/password login - [x] verify that oidc-auth-manager redirects to `returnToUrl` (preserving the hash #562) in the case of client certificate login
