redirect_uri can not be overridden

Following the same fashion as: #436

I think we are missing the redirect_uri property in type ExtraSigninRequestArgs at src/UserManager.ts

We can do so. What is your use-case? Why do you need it?

We are just migrating from old oidc-client.
Current implementation lets our user click on the login button from every page after any in-browser route change, so we are calling userManager.signinRedirect() on user demand and returning to the same url after login.

Feel free to provide a MR for that...
