'404' error when clicking on back button

[sdevalk]

Scenario: in the manage app I want to navigate between pages. I go to a collection, with an overview of objects. I then click on the card of one of the objects; the details of the object are presented. I then click on the back button, to go back to the collection again. However, then a '404' page is shown.

Fixed in #543. Note that the routing is mostly to update the URL, going back/forward will probably always bring you back to your first collection.
