Re-enable CancelResume test without flakey data size comparison checks (#1980)
Re-enable CancelResume test without flakey data size comparison checks (#1980)

Checking data sizes in NSURL::NSURLSession_DownloadTaskWithURL_WithCancelResume would intermittently cause failures, so re-enabling this test with just state checks. This is not going to catch as many types of regressions as the previous implementation but it shouldn't fail for passing code either.
