fix: remove duplicate query parameters on HTTPS redirect (#6460)

HTTPS redirection rebuilds the full URL using req.originalUrl, which
includes query parameters (see
https://expressjs.com/en/api.html#req.originalUrl). Prior to this patch,
appending the stringified query params to req.originalUrl resulted in
duplicate parameters, e.g.
wiki.js/callback?session=123&code=abc?session=123&code=abc
which caused errors when being redirected from an insecure (http://)
callback URL to a secure version when using OIDC (e.g. with keycloak).

This issue is probably rare, but in cases where HTTPS redirection is
enabled and a user tries to hit an insecure URL with query parameters,
it could cause problems.
