User should be able to click "Connect" button the first time they are redirected to login page

When the user logs out or is automatically redirected to the login page, the "Connect" button is not clickable. The user has to reload the page and then the button becomes clickable.

Start by reproducing the logout and automatic-redirect flows, comparing the first login-page load with a manual reload. Locate the login-page entry point and the Connect button handling; done means Connect is clickable immediately after either redirect path without reloading.
