Auto-upload does not work for some GPX files

[WetenSchaap]

Presumably related to #56.

Some of my gpx files (example here, same as mentioned in #56) are not uploaded automatically from the auto-upload folder. When I run the job manually I get the following error message:

          "code":"validation_required",
          "message":"Missing required value."
  }}}},
  "name":"ClientResponseError 400"
}

Other GPX-files do get uploaded as expected, so it probably has something to do with the <rte> tag again?
