"Nazaj na zbirko" is not always accurate

The dataset edit page at /dataset/edit/<dataset name> has a "Nazaj na zbirko" button at the bottom which allows going back to the dataset overview page at /dataset/<dataset name>. However, this is implemented as merely triggering the "back" function of the browser so if the user visited the page directly via address bar, the "back" can result in any page that was previously visited. This should be improved so that the button is always a link to the dataset overview.
