appveyor.yml: always publish test results (#1405)

Our test runner exit code is the number of failures. AppVeyor
misinterprets that as a failed build. Instead of uploading
test results in the "after_test:" phase, upload during the
"on_success:" and "on_failure:" phases (so that the test results
will only but uploaded once, regardless of outcome).
