putio: fix server side copy failures (400 errors)

For some unknown reason the API sometimes returns the name already
exists on a server side copy.

    {
      "error_id": null,
      "error_message": "Name already exist",
      "error_type": "NAME_ALREADY_EXIST",
      "error_uri": "http://api.put.io/v2/docs",
      "extra": {},
      "status": "ERROR",
      "status_code": 400
    }

This patch uploads to a temporary name then renames it which works
around the problem.

This was spotted by the integration tests.
