Pull request overview

This pull request adds error handling for ObjectDeletedError exceptions that can occur when an upload object is deleted by another process during project version creation. The changes add exception handling in two places: the controller's exception clause and within the Upload.clear() method itself.

Changes:

• Added ObjectDeletedError to the list of exceptions caught during project version creation
• Added try-except block in the Upload.clear() method to handle exceptions during cleanup
• Added redundant upload.clear() call in exception handler (problematic)
