The `versioning_enabled` property in the BlobField didn't have a return value, meaning it always returned None. In cases where this was interpreted as False, the allow_overwrite functionality worked correctly. But for the entries in the permissions mode_map where the bucket was versioned, and where the permission mode allowed overwrite, this failed.

This release fixes that issue.

Fixes
- Prevent permissions mode map from using None values from property

Summary

Located an extremely hard to understand bug related to the flushing of the cached existing value, in cases where multiple model objects are used simultaneously then one is refreshed from the database.

This was discovered and fixed in the WindQuest project then the fix ported over here. Kudos to windpioneers for supporting open source and funding this work!
