User Session maintenance for the root URL

[Sudhee-bsp]

Describing the bug
Login page is being loaded even though the user is logged in when navigated to the root URL https://osc-hub.herokuapp.com/
It should maintain user session across once logged-in till logged out (in-case used sessions) or cookies for a particular time (in-case cookies).

To Reproduce
Steps to reproduce the behaviour:

1. Login to the website => upon successful login will be redirected to https://osc-hub.herokuapp.com/dashboard
2. Now navigate to https://osc-hub.herokuapp.com/
3. You can see the Login page which shouldn't be loaded (as user is authenticated already)

Expected behavior
As user is logged-in the session should be maintained till logged-out, which means though the User hard navigates to the root URL (actually no one does it), website should be able to land user in https://osc-hub.herokuapp.com/dashboard

Additional context
When Logged-in, even opening the new tab in same browser, the root URL "https://osc-hub.herokuapp.com/" should be able to land the user in "https://osc-hub.herokuapp.com/dashboard" when proper session is maintained.
