Purpose
A pattern of file version corruption has emerged across multiple projects. After a new version is uploaded, the file becomes unpreviewable, undownloadable, and impossible to delete — by the user and by support. Uploading additional versions doesn't fix it; metadata updates (date modified) but the file remains unretrievable. The broken versions are stuck and block users from recovering a working file.
Looks like what’s happening is if you check https://api.osf.io/v2/files/f42sc/ and look at its file versions https://api.osf.io/v2/files/697ec8ac74e08d03dccd76ea/versions/ we have multiple version 2s of the same file that seem identical but have a sliiightly different date_created, and that's causing problems with the system. We need to prevent that from happening and clean the data for the existing issues.
Changes
make create_version to avoid file version duplicates and get_version to return single file version;
create management command to dedupe (delete file versions duplicates);
