Fix finalization for json_objectagg and friends Commit f4fb45d15c misguidedly tried to free some state during aggregate finalization for json_objectagg. This resulted in attempts to access freed memory, especially when the function is used as a window function. Commit 4eb9798879 attempted to ameliorate that, but in fact it should just be ripped out, which is done here. Also add some regression tests for json_objectagg in various flavors as a window function.
