Package appveyor artifacts after test

Artifacts apparently get listed before the before_deploy step.
Not having them ready at that point results in an error message:

  No artifacts found matching
  'build\stage\gagern\node-libtidy\releases\download\**\*.tar.gz' path
  No artifacts were published.
  Make sure you have specified correct artifacts filter.
