Observed behavior

This issue was first reported in https://community.learningequality.org/t/zipped-html-app-are-not-publishing/3874
If I create a brand new channel and upload a single .zip file then when I attempt to publish the channel it can't be published and there are no errors in the console.
If I open the channel details then I can see that the value in "Total resources" is 0.
If I upload any of the other supported file types along with the already imported zip file, then I can publish the channel but if I try to import it in Kolibri the zip file will not be imported.

Here's a link to a channel with a zip file which can't be published: https://studio.learningequality.org/en/channels/767b1798e5304c559792481861260d38/#/ff3f3b5a43b94ca299573b32eb84bb00
Note that I can click on the resource and preview it.

Expected behavior

It should be possible to upload a valid .zip file and publish the channel and then import the HTML resource in Kolibri.

Steps to reproduce the issue

1. Sign in to Studio
2. Create a new channel and upload a .zip file
3. Try to publish the channel with the single .zip file
4. Upload other supported files and publish the channel
5. Try to import it in Kolibri
