Fix JsonExpr deparsing to emit QUOTES and WRAPPER correctly Currently, get_json_expr_options() does not emit the default values for QUOTES (KEEP QUOTES) and WRAPPER (WITHOUT WRAPPER). That causes the deparsed JSON_TABLE() columns, such as those contained in a a view's query, to behave differently when executed than the original definition. That's because the rules encoded in transformJsonTableColumns() will choose either JSON_VALUE() or JSON_QUERY() as implementation to execute a given column's path expression depending on the QUOTES and WRAPPER specificationd and they have slightly different semantics.
