Test failures

[utkarsh2102]

Hey,

Attaching the logs of test failures, could you take a look at it?

Pending: (Failures listed here are expected and do not affect your suite's status)

  1) Paperclip Attachment with no generated thumbnails allows us to selectively create each thumbnail
     # 	#reprocess! calls #assign which calls Paperclip.io_adapters.for 
	which creates the tempfile. #assign then calls #post_process_file which
	calls MediaTypeSpoofDetectionValidator#validate_each which calls 
	Paperclip.io_adapters.for, which creates another tempfile. That first
	tempfile is the one that leaks.

Failures:

  1) Paperclip::Storage::S3 An attachment with S3 storage when assigned will retry to save again but back off on SlowDown
     Failure/Error:

         raises(Aws::S3::Errors::SlowDown.new(stub,
                                              stub(status: 503, body: "")))

  2) Paperclip::Storage::S3 An attachment with S3 storage when assigned and saved without a bucket succeeds
