As a User I want to be redirected to the homepage when I log in

[sgobotta]

There is currently a weird experience when a user logs in. It is not redirected anywhere, it just gains access to the Core component. So if a user is in the /xxx view when logging out, then (without refreshing the browser) a user that logs in stays in the /xxx directory.
This can lead to unexpected errors. For example, the user that just logged in has no access to the /xxx view and he/she didn't even have the intention to visit that page.
This proposal focus on a simple redirection to the homepage (/) everytime a user logs in.
