Title: Fix (suggestion?) : StoreAssetWorker throws an exception when using remove_column! method from carrierwave then upload a file again

This bug (afaik) only occurs when the Store worker is interrupted somewhere during processing
(i'm processing video so the processing time is very long).
When this happens, the column_tmp file is never set to nil and the next StoreAssetWorker won't work correctly.
