Sorry to do this, but these failures are totally obscuring test output.

Joe, what is the right way to deal with this? we had decided on skipping it if
it is a short test in:
https://codereview.chromium.org/779633003/diff/60001/ct/go/util/gs_test.go#ne...

IMO I should still be able to run the tests without -short and expect them to
pass instead of panicking.

         // Skip if we are running short tests because this test needs a valid
         // google_storage_token.data file with read write access.
         if testing.Short() {
                 t.Skip("Skipping test because we are running in short mode.")
         }

         client, _ := GetOAuthClient()
         gs, err := NewGsUtil(client)
