Title: serialize Date objects properly with ko.toJS

`ko.toJS` was not serializing `Date` objects properly. this was because it was trying to recurse over properties of Dates when an instance of a `Date` should have been considered to not have properties that can be recursed into.

i put the test case and fix into separate changesets so that you can update to the changeset with the test case and see the failure and then update to the fix and see that its fixed.
