There is an on_replace trigger in _truncate space protecting from _bucket space clearance. The trigger wasn't ready to _truncate having deletions. It happens when any previously truncated space gets deleted.
As a result, _truncate didn't allow any deletions and its tuples were just staying permanently.
The patch makes the storage ignore _truncate deletions. They don't affect bucket rows anyway.
