Unembargo process results in error due to incomplete uploads

[kabilar]

As reported by a user on August 27 via email to [email protected], when umembargoing a Dandiset an error occurs which turns out to be a result of incomplete uploads. The error message displayed to the user upon pressing UNEMBARGO is:

Sorry, something went wrong on our side (the developers have been notified). Please try that operation again later.

@jjnesbitt found that the API was returning a 400 error when attempting to unembargo. To resolve, Jake manually removed the uploads after confirmation from the user that the uploads were not necessary. We should catch this case of incomplete/interrupted uploads, provide this feedback directly to the user, and provide instructions on how to resolve.

Thank you.
