* Factor out a common TestHtmlParser Looks like I'm doing this in a few different places. * Improve OIDC login test Complete the OIDC login flow, rather than giving up halfway through. * Ensure that OIDC login works with multiple OIDC providers * Fix bugs in handling clientRedirectUrl - don't drop duplicate query-params, or params with no value - allow utf-8 in query-params
