Inside nth argument: replace query_description with deepcopy that is missing nth

for these kind of queries nth decoding  Should happen inside the transformation function not inside process_line. These was causing problems, because queries that they don't specify an inside index("inside first argument 1" As opposed to "inside 1 first argument 1") Were not searching All of the arguments of the parent call But only the one with index 1
