Remove file name from single notification page

Having a file name for single messages made sense when they were called
‘Test message’. They made a bit of sense when single messages still had
a file, which had to be called _something_.

Now that individual messages don’t come from a file, and don’t land you
on a page that looks like a ‘report’.
