Describe the bug
It looks like any form with media hosted on Aggregate is failing to load those media files. For a form with images this fails silently. For a form with external data this fails with an "Unable to auto-detect delimiting character; defaulted to ','" error.

To Reproduce

  1. get URL to aggregate-hosted survey: curl --user enketorules: -d "server_url=https://enketo-aggregate.appspot.com&form_id=widgets_on_pages" http://localhost:8005/api/v2/survey/
  2. load the URL
  3. inspect failed media download(s) in network tab, see something like:
<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>400 Insuffiecent Parameters Received</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Insuffiecent Parameters Received</h1>
</body></html>

Expected behavior
Form to load with media resources.

Additional context
Link to media manifest on Aggregate for this form: https://enketo-aggregate.appspot.com/xformsManifest?formId=widgets_on_pages

I looks like a link to a download url such as https://enketo-aggregate.appspot.com/xformsDownload?blobKey=aggregate.opendatakit.org%3AFormInfo%5B%40version%3D1+and+%40uiVersion%3D0%5D%2F_form_info%5B%40key%3Dmd5%3Acc0a52104c3e1028d7b23cca46837e72%5D%2F_form_info_fileset%5B%40ordinal%3D1%5D%2FmanifestFileset%5B%40ordinal%3D1%5D&as_attachment=true no longer survives into the transformation result.

I believe the whole query part of the download URL is stripped out.

A simpler form without external data: curl --user enketorules: -d "server_url=https://enketo-aggregate.appspot.com&form_id=big-image" http://localhost:8005/api/v2/survey

The regression occurred in 3.0.2

Thanks for filing this @MartijnR. I believe I've found the cause: in enketo/enketo-transformer#111, when provided an absolute/relative URL, only the path is returned. This is obviously incorrect, thankfully it should be a trivial fix.

@eyelidlessness Is this just an issue with Aggregate or does it affect Central? And if it does, what types of forms does it affect? I guess what I'm asking is that should we plan a hot fix for Central?

@yanokwa It affects anything that uses query parameters in media mappings. I haven't seen that in Central but I don't know whether that's possible.

@lognaturel Says it's not an issue for Central (whew!). @MartijnR how urgently do you need this released?

Not urgent! Thanks for checking.
