ArgoCD UI should redirect to the /login page when user not logged in

Checklist:

[x] I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
[x] I've included steps to reproduce the bug.
[x] I've pasted the output of argocd version.

Describe the bug

The ArgoCD UI replaces the browser history to navigate to /login?return_url=... without reloading the page. This behaviour is causing issues for us since we want to rewrite the /login location to /auth/login in our ingress controller. It would help immensely if the history.push was replaced by a window.location.href here: https://github.com/argoproj/argo-cd/blob/master/ui/src/app/app.tsx#L270

Not sure if this should be a feature request or a bug.

To Reproduce

Navigate to the / location of the ArgoCD UI and notice that the browser location has been updated to /login?return_url=... without a page reload. Checking the ingress controller logs shows that no calls were made to argocd-server.

Expected behavior

Ideally this should trigger a page reload to /login?return_url=... instead of just manipulating the browser history.
