Redirect the user if they're already logged in

Similar to when the domain root url is accessed, if the user is
already logged in do not show them the login page nor ask for their
credentials. This avoids users being misled into thinking they can
open multiple sessions in parallel, and is in line with how most web
applications handle this.
