Motivation
Special:ImportFile has an "import" button, and a "cancel" button. Right now, when clicking the cancel button, nothing happens. However, when clicking on cancel, users should be redirected to the file page they came from, to offer a "safe" way of canceling the import. Just closing the tab might make some people uncomfortable, since they would not know that nothing has changed in the background yet.
Task
- When users click on "Cancel", they are redirected to the page they orginally come from.
