Immutable js data is deserialized with errors

[jsmonkey]

Hi guys,

I'm using redux-persist which uses remotedev-serialize which uses your package for (de)serialization of the Immutable js app state.

When several properties in the object tree have the same values then jsan tries to reuse first entry of the value using references to it in other places.

For example:

obj = {
    prop1: 'sample value',
    prop2:  {
        prop3: 'sample value'
    }
}

after serialization will be

{ "prop1": "sample value", "prop2":  { "prop3": "$.prop1" }}

But with Immutable js during the serialization remotedev-serialize with help of jsan converts immutable js structures into it's own representation and serializes it.

So the references for the same values are built over the converted structure instead of the original Immutable js structures.

And during the deserialization jsan first transforms its own representation to the original Immutable js structure and only after that trying to resolve references for the same values but fails and always returns undefined cuz such references for its own representation can't be resolved on the original Immutable js structure.

	parsed = JSON.parse(text, reviver);
	}
	if (needsRetrocycle) {
	parsed = cycle.retrocycle(parsed);
	}

I've created PR with fix.

This should be closed via #7 right?
