Fix value property assignment order

[jedel1043]

This PR reorders assignments evaluation to conform to the spec... however, it seems to be uncertain if the new assignment semantics are intended or a bug on the spec (see tc39/ecma262#2659 and tc39/test262#3407).

If it's indeed a bug on the spec, this should be closed in favour of the current semantics. Otherwise, this can be merged.

Per the previous explanation, this is blocked on tc39/ecma262#2659

Closing since it was decided that the old behaviour was the correct one.
