If there's a valid session already present(i.e. user has already logged-in).
Then visiting the login page again(without singing-out) should redirect the user to dashboard page.

Steps to Reproduce:
1. Login with any user
2. Change the url from whatever to /users/login
Example: if url is https://localhost:3000/hosts
then change it to
https://localhost:3000/users/login
3. Hit enter

Actual results:
User should see dashboard or home page.

Expected results:
Login page is visible. Which should not be the case.
