Steps to reproduce:

1. Create OauthAuthorizationUri with state

What should happen:

https://oauth.bunq.com/auth?response_type=code&redirect_uri=redirecturi&client_id=client_id&state=state

What happens:

No & that divides the client_id and state parameters resulting in incorrect hash for clientId.

The URL should be:
https://oauth.bunq.com/auth?response_type=code&redirect_uri=redirecturi&client_id=client_idstate=state
