Remove authParams from getAuthorizeUrl

[gillyhl]

This PR removes the need for authParams to be specified in the authorisation URL generated, considering the request object holds all that information already.

Can we also change the docs to reflect this? https://docs.moneyhubenterprise.com/docs/authentication#authorization-endpoint

Has this been tested with the latest version of Identity service? just to make sure that it is not expecting anything in the auth params when the request object is present

I tried generating an auth url and I can see that is adding scope only as openid in the auth url but the request object has all of the right scopes, will this not cause issues?
I can also see that is still adding client_id, response_type and redirect_url but those might be required according to the spec
