Inconsistent redirect from root url

The redirect, which happens at the root of membership.eclipse.org can be inconsistent depending on whether you have logged into the portal at some point in the past.

Steps to Reproduce

1. Clear local storage logInFrom entry
2. Visit membership.eclipse.org
3. You should notice you are being redirected to membership.eclipse.org/application/sign-in
4. Navigate to membership.eclipse.org/portal/login and log in
5. Log out
6. Navigate to membership.eclipse.org
7. You should notice you are being redirected to membership.eclipse.org/portal/login

This will forever be true until the user clears their local storage.

We could consider using session storage instead of local storage. This way the default behaviour (membership application login redirect) will be much more common.
