Add a test case test_fetch_premirror_use_downloadfilename_to_fetch to ensure
that 'downloadfilename' is used when fetching from premirror.
Although the other two previous test cases, test_fetch_premirror_specify_downloadfilename_regex_uri
and test_fetch_premirror_specify_downloadfilename_specific_uri already
implicitly contain such verification, we still need to add a very clear
case to ensure no regression.
