Fix #1907 where the never-ending loop prevention used a coersion comparison which sometimes dropped values incorrectly. Also fixed a bug where on deep copies the target copied over itself (i = 2 addition). Last made code handle the case when a property might have a string in it that should be overwritten by an object.
