[FIX] Redirect to default URL after 1FA when default policy is one_factor. (#611)
* Redirect to default URL after 1FA when default policy is one_factor.

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.

* Update users.yml

* Fix permissions issue causing suite test failure
