User is now redirected to the default redirection URL after 1FA if
the default policy is set to one_factor and there is no target URL
or if the target URL is unsafe.
Also, if the default policy is set to one_factor and the user is already
authenticated, if she visits the login portal, the 'already authenticated'
view is displayed with a logout button.
This fixes#581.
