REVISION SUMMARY
  It looks like shared-mime-info, and thus QMimeDatabase, cannot detect-by-content tar archives created with the --format=v7 flag.
  Instead of adding another exception (like we did for ISO files), let's just use the mime detected from the extension if the one from content could not be determined.
  
  BUG: 355955
  FIXED-IN: 15.12.0

TEST PLAN
  Opening uncompressed tar v7 archives now works. Opening ISO files still works.
